That way no one but you can access the things you have written. What I would do is list down every cheating sign I observed from my cheating spouse and the results of using the following methods and gadgets.


Ways to catch a cheating spouse

1.Cell Phone Trackers

Have you ever heard of these? These are programs which you install on your cellphones and have it collect data for you. That data is then sent to a server via the internet which you can access through your home computer or laptop. After manual installation on your phone, you can then leave these cell phone spies alone and just remotely access the data. Most of these work for all the latest mobile phones and the quality ones are always made to be undetectable. Their price ranges from $10 dollars a month, to $60 dollars per quarter. Very affordable, very effective. A top pick for catching a spouse who always has a mobilephone handy. We will not be talking about remotely activated mobilephones[1], those are costly and should not be recommended to anyone who is not a professional spy. It is also illegal to monitor other people’s mobile phones, you should only monitor a phone that you own. What we will talk about are cellphone spies that have text monitoring services as well as GPS trackers. Read the full Cell Phone Tracker article.

2. Keyloggershow to catch a cheating spouse

Keyloggers are devices or software that monitor keystrokes on your computer, which is called keystroke logging[2]. Keyloggers can be useful to you if your suspected cheater is on the computer or laptop a lot (nowadays, who isn’t). The only downside to this method of catching a spouse is that laptops have no other option other than using software keyloggers which you need to install because it wouldn’t make sense to add a hardware keylogger onto a  laptop. A hardware keylogger is more suitable for desktop computers. It is a small device that needs no installation, other than physically inserting it into your keyboard slot located at the back of the CPU. Downside of the hardware keylogger vs the software keylogger is storage space. With hardware keyloggers you are allotted a certain amount of space depending on the type of keylogger used. Software keyloggers make use of the computer or laptops own storage space, so the difference is immense considering hardware keyloggers only reach up to 12 gigabytes and start costing upwards of $50. Please remember that you should never monitor a laptop or computer that is not yours. Read the full Catch a cheating spouse with Keyloggers article.

3. GPS

Or Global Positioning Systems[3], is a way of tracking a device remotely from your pc or laptop. These devices are commonly attached to cars, but recent cellphone spies are so advanced that they have added this functionality to their software. The commonly found GPS devices will let you monitor the device using Google Maps, which makes it a very very powerful tool. Google Maps even allow you to view webcams located in those areas, and get the complete directions to get to that area, from a chosen area of origin (your home for example). The most solid way of busting the lies told to you by your spouse. No more 5 hour long shopping trips, GPS devices will tell you exactly where their went and for how long. Again, this should never be used to track a car that you do not own. It is illegal to GPS track anything but your own property. Read the full GPS Vehicle Tracking Devices article.

4. Reverse Phone Lookups

Also called Reverse telephone directory[4], is a service that lets you track a phone number, be it cellphone or home phone. You can now reverse phone lookup those unknown numbers that keep calling you! The downside is, some people can pay to get removed off of the reverse phone lookup database. Ever wonder how that telemarketer got your phone number? They used the reverse telephone directory. So if you want your details kept off, you’ll have to pay a fee. Another downside is that you will have to pay a fee to access full reports, I have not found a website that offers reverse phone lookups for free. The common details provided are Phone owner’s full name, address, what type of phone (cellphone or landline), and other associated phone numbers. Read the full Reverse Phone Lookups article.

5. Image Tracking

This is simply a search engine, for pictures. Something that is fairly new technology. It’s not the same as google that you type words, instead you show the search engine images. It also may be referred to as Content-Based Image Retrieval (CBIR)[5]. This is useful if you want to run your spouse’s pictures on a CBIR database to see where those pictures are listed on the internet. There is no fee for this service. There are however, limitation. For example, you find your spouse’s picture and they are with an unknown person who they won’t tell you about so you decide to do a search. You will not find that picture online if that picture is saved somewhere on Facebook or Multiply or any other type of social site that is set to private. Only public websites work, and as of now there are no CBIR companies that are big enough (say like google), who scan the entire internet. Read the full Reverse Image Tracking article

6. Video Surveillance Equipment

Hidden cameras are another effective solution to cheaters who have “visitors” at home while you are away. There are different types of surveillance equipment, and the hidden cameras are a little bit on the expensive side ($100+). What you’ll want to use is something that is small, and motion activated so you do not have to risk running out of storage for capturing video (and audio if you choose). This method has been made famous by a hit TV series called “Cheaters”, with Joey Greco.

7. Private investigators

Private eyes are the last thing you should consider if you do not have the cash. They are the most expensive way to catch a cheating spouse, but they are also the most reliable way. All you do is pay, and they will have every tool described here and more to track and document your cheating spouse’s activities. It is not uncommon to receive a bill of $3k or more for hiring a P.I. to track someone out of town for several days. A private investigator may also provide assistance to your attorney in civil cases such as helping you get child custody, premarital screening, and proving whether or not your spouse is cheating on your or not[6].

8. Setting traps

Something often overlooked, setting simple “traps” can help tell us if there are things going on in our home when we are away. A trap can be as simple as putting a thin see through tape at the back end of your toilet seat. If you are expecting no one to be home, and you apply this toilet seat trap, the most likely situation you would walk into when you get home is the tape would still be there. But if that tape is broken, you’ll know someone has been in your bathroom. Simple, free, effective. Read the full Free Ways To Catch Your Cheating Spouse article.


Other Ways To Catch A Cheating Spouse That Is –NOT– Recommended

1. Lie Detector Tests

These are not just expensive, they’re subjective as well. The will of the examiner and how nervous the person taking the test is what will determine whether or not they will look guilty or innocent according to the lie detector. People react differently when lying, and lie detector test examiners have different approaches in “controlling” your response. Lie detectors are not even supported by the scientific community. Trickery, not science, is what is used to get the “truth” out of you. If you would like to find out more about why a lie detectors should never be used, read this book “The Lie Behind The Lie Detector“[7] by George W. Maschke and Gino J. Scalabrini from

2. Impersonation

Calling up credit card companies, banks, phone companies, internet service providers and pretending to be someone you’re not is impersonation, or if you do it online it’s called Phishing[8]. Say for example you found out the identity of the person your spouse is cheating on you with, then you use his or her name and pretend to be them in order to phish information, you can and most probably will get sued if they find out about it. Stick to watching for signs of cheating and focusing on your own spouse. Leave the other person alone, avoid all interaction unless you are going to confront them with legally acquired proof that they have been cheating with your spouse.

Signs Of A Cheating Spouse

signs of a cheating spouseYour spouse is cheating on you, or at least that’s what the voice in the back of your head is saying. Are you being paranoid, or have you just really been observing some typical signs of a cheating spouse? When you have been together with your spouse or life partner for a significant amount of time, you start picking up on their subtle “tell tale” signs of lying, or “stress reactions”. It’s easy to tell when your spouse is trying to deceive you. But what if you’re spouse is such a terrific liar they show no signs of cheating at all?  Maybe you are just too trusting and would never expect them to lie to you, or even worse, cheat on you. It happens all the time. I’m sure you have stories of your own that you’ve heard from friends, family members, co-workers about people they know who seemed like they were so perfect for each other, but then had infidelity problems. You never thought that could happen to you? Here’s some advice on cheating signs based on our experiences(my own, my spouse, my friends, and other reader contributions). If you would like to contribute your own to this list, feel free to do so in the comments. It’s anonymous, we don’t require any personal information from you.

Cheating Signs

In no particular order, these are some common Signs of Cheating :

I want to look more attractive

Since when has your spouse had a sudden urge to go to the gym? Does your husband go to the gym? Does your wife want to stay slim? What reason would they have other than trying to attract, or wanting to impress the opposite sex. If you’ve been together for several years, and now is the only time your spouse has ever done this, and gave you no reason at all except for “I felt like it”, this should look suspicious to you. Some cheating spouses may use this new found “gym” time to be an excuse to be out of the house for several hours without worrying you, or looking suspicious. For women, this could mean an increase in buying new clothing, more revealing than the usual clothes they wear. For men, it could be as simple as grooming their facial hair, getting a new haircut. Things to watch out for are sudden changes that they can’t explain, not a major red flag but still useful to keep track of.

The 5 hour shopping trip

This is common among women. You know how your wife shops for hours and hours, and you stay home, then she comes back with tons of shopping bags or groceries? When this happens and she comes back with little to no shopping bags or groceries, can’t show you a receipt, something is wrong. Applies to both husband wife, the 5 hour shopping trip is a very weak excuse to give your spouse, and is an obvious sign of deception. You can easily tell if they are lying when they can’t explain why it took 5 hours. Trusting spouses will usually believe “window shopping” or “I ran into a friend”. If this happens too often, you better do some investigating. Obvious signs that they are lying is they are “dressed to impress” and heading out for a simple “trip to the grocery”.

First stop, shower

Another common cheating sign. When a spouse gets home, don’t they usually look for their spouse and give them attention? Most of the time when my hubby gets home, he heads straight for me, then the kitchen, then back to me and we chat a little before we eat dinner. If you and your spouse have similar rituals as me and my spouse do, it will certainly seem out of place when your spouse just yells “I’m home!” and heads straight for the bathroom. Cheating spouses do this in order to fully inspect themselves for any traces of infidelity on their clothing, and themselves. Washing the guilt away is just as easy as taking a shower for some cold blooded liars.

Tolerates flirts or acts flirty

Having been together with your spouse for some time now, you know exactly how they act towards people who flirt with them, or try to hit on them. If your wife used to ignore people that try to flirt with her, or even scold them, but now you notice her laugh and “play along”, then you should be suspicious. Same goes for husbands who initiate the flirting. Both tolerating flirts, and initiating flirts are not acceptable behaviors in a regular marriage. If you are married, the only person you flirt with your spouse. Some people may have an open relationship, where both parties agree to open flirting, but if this happens to you and you don’t have an agreement that you can flirt with other people of the opposite sex, your mate may be looking for another.

“Do we have toooo?”

If you have a kid, you most likely have heard this line several times already. This is the general attitude of someone who does not want to be part of what is happening right now, and wants to do something else. If your spouse shows the same reluctance when you want to do something together, you may have competition for your spouse’s attention. You notice when your spouse gets home from whatever it is you wanted to do, they either never let it down how much they hated it or were bored, or they immediately head to the computer. Which leads me to the next sign..

Technologically hooked

Cheaters often use cellphones, computers, and laptops to communicate with each other. This is both an advantage and a disadvantage to them. It’s so easy to monitor these devices using  cellphone spies, keyloggers, or even GPS trackers. But you don’t need those if you notice your spouse immediately comes home, and heads straight for the computer. Hides the screen from you. Always has a cellphone in their hand. Try and asking who they are communicating with, and they’ll usually say it’s no one, it’s just a friend, or some other diversion tactics they may have up their sleeves. If you don’t know who they are talking to, you should find out. Find out as soon as you can, waiting for problems to fix themselves is never good. I learned this from my mother, who was also cheated on by my father when they were in their mid 40-s. The affair lasted close to a year and she had NO idea until she observed some of the signs I am now describing here. This next one is one of the biggest signs that helped her. But a GPS Tracker on his cellphone is what gave her 100% undeniable proof of cheating. My mother is brave and she actually tailed the GPS tracker with her car.

Inappropriate jokes about cheating

This is what my father started doing when he was having an affair. Maybe in his arrogant mind, he thought he was sort of “confessing”, or maybe he was just trying to lighten the guilt of cheating on his wife of 20 years. He used to make vague excuses, and as he was about to leave my mother would ask “where are you headed off to?” “to my other woman”, he’d say, and other times similar, dirtier versions of that. At first my mom just laughed it off, because this was how their relationship was, a lot of kidding around and fooling each other. She most likely put it all together when his drinking buddies never mentioned their poker games anymore, and his paycheck never increased with all the out of town business trips. He still continued with the inappropriate jokes about cheating on her though until they fought about it and she said it wasn’t funny anymore.

In bed: Complete shut out, or the exact opposite

This would depend on your current, or lack thereof, sexual relationship. Sometimes a cheater will want nothing to do with you in bed, saving themselves for their new found mate. Other times it could be the complete polar opposite of that, and the cheater becomes experimentative. Trying new things they could have learned from their new partner. I personally never experienced the latter, it was just mostly cold silence in the bedroom aside from the TV. Other people often experience the latter, which is why they are more surprised to find out their spouse has been cheating because they think having regular relations in the bedroom means their partners needs are fully sated.

Did you use to share everything? Not anymore

You used to know your spouse’s email passwords, bank account PINs, facebook account passwords etc, but they suddenly changed it without telling you why or giving you a reason. This sudden need for privacy should alarm you. Maybe if you are not in a serious relationship yet, it’s fine, but if you are married, it’s suspicious. Couples who have been together long enough know and share everything about themselves. Hiding email or conversations on the internet is a big red flag if they can’t give you a reasonable explanation for their sudden need of privacy.

The classic contraception situation

You had a surgery (vasectomy, tubal ligation) to stop you from having any accidental pregnancies, but you found some condoms, morning after pills, or other form of contraception in your car or in an article of clothing from your spouse. This obviously is going to shock you because your spouse most likely knows about your surgery, and knows you don’t need any form of birth control anymore. Obviously a cheater would lie by saying the usual lines like “it’s not mine, its my friend’s!” “Jesus you are so paranoid, *name* must have accidentally left it here” or some other cliche excuse. So before asking your spouse whose is it, try and bait them first and find out if they’ve had any other people ride with them, then show the contraception.

I’m not a lover, I’m a fighter!

Fighting become a common thing in your relationship? Do you and your husband or wife fight over inane things, and end up in a yelling competition over who left the toilet seat up? Stupid little things turning into a full blown fight may just be another excuse they are looking for to leave the house! Especially if it’s always them starting the fights. If this inane fighting is becoming a weekly occurrence, resulting in your spouse having a reason to “cool off” away from you, and your home, next time you fight try doing the opposite. DON’T fight back and just agree, that should cut their excuse to leave. If they keep prodding and trying to find a reason to “cool off”, you know something’s wrong.

“Nah, it’ll bore you to death where I work”

In other words, “Nah, I don’t want you to see me and how I interact with a certain someone from work”. Wouldn’t you want your spouse picking you up from work, or paying you a visit when you have free time? Like lunch for example. If you suspect your spouse cheating with a workmate, try asking them out on a lunch date and say you’ll be around the area. Of course you’ll have to be around the area to make it look like you’re not trying to spy on them. Typical reaction would of a cheater would be to fire off another cliche “I’m too busy honey, I can’t” “I’ll be doing something at lunch” “I already have a lunch meeting” “We can do it some other time”.

Working for free

Not really working for free, but that’s what it seems like when your spouse says they have overtime, extra work, a new project but never show a cent earned from their extracurricular activities. Unless, obviously, if your spouse volunteers for charities. If your spouse volunteers for charities, and never really talks about it in detail when you ask, you have almost no chance of really finding out the truth unless you yourself join the charity. If you offer to help, and your spouse reacts negatively, then that is a sign of deception, and should raise red flags. Get yourself involved!

Guilt driven niceness

You for no reason getting random gifts from your spouse? Is he suddenly sweeter, or takes you out to dinner? Does she cook your favorite meal, or offer to give you a massage? Sometimes that’s what a cheater does to convince themselves that what they are doing is okay because “I love my spouse, the other person is just for fun” in their mind justifies their actions. Being nice to you is somehow equated to “loving” you, while cheating on you is equated to “just fun” for them, and not massive disrespect to you and your relationship.

“I can hear you breathing you psycho!”

Getting more and more callers that don’t answer when you pickup? A classic, seen in almost any movie that has some infidelity going on. If you get random phone calls that don’t answer when you pickup, but your spouse never does, it could mean it’s their cheat partner calling them. Think about this, when was the actual last time you have received a wrong number? Normally, I probably get at most two to three wrong numbers in a year! If it’s happening once a month, you might have someone after your spouse.

Phone bill fluctuations

Getting long distance charges? Repeated midnight phone calls, which they deny or say “I can’t remember who, I don’t think I called anyone” or something similar is an obvious sign of cheating. You better confront them after this, since you already have solid undeniable proof that they are lying. A good cheater will not use the house phone, or even the cellphone. They will use skype or something similar to keep in contact with their cheat partner. Cellphones nowadays are common and cheap, so don’t be surprised if you find some hidden cellphones that are being used behind your back.

Monthly spending trends, skyrocketing

Being in a relationship, you both share financial details with each other so it’s easy to spot this. If you suspect your spouse of cheating, keep track of their monthly spendings and I can almost guarantee that a cheater will always have their spendings go higher and higher. This was true for my mom, and it was true for myself. My father spent an awful lot more money on gas and other things that were left unexplained. Since my mom loved(still does actually) him so much, she just trusted him. My ex-husband did not spend an awful lot more on gas, but he did spend on hotel rooms which I found out by look at the credit card bills. Even if he lied about it, I had verifiable evidence in form of the bills, and his exact GPS location. Even without the GPS device, it would have been obvious that he was cheating because of the bills alone. He sealed his own grave because I baited him and he said he was at a friend’s house and was too drunk to drive home. He has no friends who own hotels.

Missing wedding ring

Seems like this is a no brainer, right? Removing the wedding ring when pursuing other men/women is the typical thing a cheating spouse would do. But there are some people who keep the wedding ring on, and for some reason this heightens the thrill of their affair. Also some women have a silly belief that when a man is married already, they are somehow better in bed. This is a stupid belief, it’s as simple as this: you are GREEDY. You want something you can’t have and don’t care who you have to step on to get what you want.

I’m going to the gym, time to pack my mini skirt

When your spouse, husband or wife, packs clothing, try to check on or offer to help them pack. Sometimes you’ll see them packing things that really do not fit in to where they are supposedly going. Mini skirt being packed when going to the gym? Semi formal clothes being packed in the trunk of your car for a supposed “fishing trip” with the guys? Doesn’t add up. If you find sexy lingerie packed in your wife’s business trip baggage, you better confront her!

The car does not lie

There are so many ways to make the car “speak”. You can check the seat position (both passenger and driver seat), has it been moved from where it normally should be? Yes? Possible cheating, but unlikely cause most passengers move those seats anyway. Millage of your car, this is vital. If you already have that feeling that your spouse is cheating, along with monitoring their monthly spendings, start monitoring the millage they use every day, week, or month. Another verifiable evidence coupled with spending on gas money. There are also certain tests (semen test kits) that you can purchase online that you could possibly use on your car’s seats.

Like animals, we are programmed to have routines

Any sudden change in routine with no real story to back up why they changed their routine could mean they are trying to hide something. A cheating spouse changes routines suddenly, a loving spouse will change routines WITH you and give you a reason for it. Like exercising for example, a cheating spouse would just one day tell you “I’m off to the gym” with no prior notice besides that day they they were planning to go to the gym. A normal, loyal spouse will try to convince you to join them, so both of you can start getting fitter and live healthier lives together. Another example would be shopping, cheating spouse: “I’m going shopping, be back soon”, loyal spouse: “Lets go shopping, I want to show you something I like”.

Because my gut says so

One of the best signs your spouse could be cheating on you, is your own intuition telling you it could be a possibility. Who knows your spouse better than you yourself, right? All the tools and signs of cheating we discuss in this site to catch a cheating spouse is only used for confirming your beliefs, helping you spot more lies, and collecting evidence. The initial feeling you got that your spouse could be cheating is what drove you here, looking for confirmation based on other people’s experience. That is the biggest red flag of all, if YOU think your spouse is cheating, you probably might be dead on.


Before You Confront a Cheater

Observe The Suspected Cheater

Cheating spouses signs should NOT be the basis for you to confront your husband or wife regarding an affair. This is just anti cheating advice and should serve as a guideline to help you detect an affair, not as your “proof”. We always recommend that you back up your accusations before you even think of confronting a cheater. A good cheater, is a good liar; don’t underestimate the things a liar will say to get out of the hot seat. Get enough irrefutable evidence of your cheating spouse, think of any excuses they may come up with and answer them with the evidence you collected.

Gather Evidence Of Infidelity

Such evidence could include transcripts you caught on your home computer via keylogger, the location of their car via GPS tracking, or other ways described in the how to catch a cheating spouse article. Your goal should be to make them admit to cheating. There’s no way that anyone can argue their way out of data gathered from a GPS tracker, or a mobile phone tracker, and most probably if you do not have any evidence they will just accuse you of being paranoid and blame you for everything. If you do have evidence of an affair and they still won’t admit it, take that as a sign that the relationship may not be salvageable; don’t be delusional and think the problem will fix itself, it won’t. That may sound cruel to you, but that is how you should react. Aim for things that you can achieve, not things that you want to happen. If your spouse wants to lie and continue to cheat, there is nothing you can do about it, it’s out of your control. What you can do is stop wasting your time on the liar and start finding ways to improve the quality of your life.
