While there can be an innocent explanation for almost anything, some signs of a cheating wife are pretty easy to spot, if you are paying any attention at all. If you notice credit card statements or receipts showing purchases of lingerie, sex toys, etc., of find such items and/or condoms in her possession, but these items are never part of your activities with her, there's good reason to be suspicious.

One of the more common signs of a cheating wife is when she suddenly starts being very secretive. If she engages in hushed phone calls or tries to only converse on the phone in private, or if you notice she spends a lot of time online but the browsing history on your computer has been erased, there is cause to be suspicious. There is of course the possibility that she's trying to plan a surprise party for you or something like that, so don't jump to conclusions too quickly. It is also possible that she's satisfying some fantasy online that she would never explore in the real world, but such behavior still suggests some dissatisfaction with your relationship.

Changes in sexual behavior can also be signs of a cheating wife. Decreased desire for sex could be due to any number of factors, including stress or fatigue, but if your wife suddenly starts avoiding having sex, it is a cause for concern. Some women who are cheating will actually seek out sex with their spouses more often. This might be out of guilt or as a deliberate ploy to keep the husband from suspecting her extracurricular activities. Increased sex drive can also result from other things like hormonal changes, so it is best not to take that in itself as a sign of infidelity.

In addition to changes in her desire for sex, there may also be changes in her desire for certain sexual positions or changes in how she behaves during intimacy. Perhaps you notice that she kisses differently, or that she is wanting to use sex positions that you've never done before. Of course, she may simply be exploring ideas she got from a magazine article or a friend, but big changes in what she does during sex is at least a sign that you need to pay close attention to what's going on.

It can be easy to miss the signs of a cheating wife if she's spending a lot of time with a female friend. But when your wife is out with her friend all the time, including late at night and on the weekends, there is cause to wonder what's up. Your wife's friend may be her alibi for slipping out to see another man, or there's also the possibility that the female friend is the person she's cheating on you with.

When you suspect that your wife may be cheating on you, it is a good idea to try to stay as calm as possible and carefully take the necessary steps to first find out exactly what's going on, and then to figure out what you want to do about it if your wife is cheating on you. The emotions that come up can cause you to rush into actions you might later regret. That's why you need to do your best to stay calm and first obtain foolproof evidence that she is actually cheating.

There are several ways to do this, and there are quite a number of online resources to help you do it yourself. The thing you have to realize is that you are emotionally involved in this, and chances are you are not as skilled as a professional investigator, so if you are going to collect your own evidence, you need a system that is simple to implement and allows you to get the evidence you need without risking getting caught investigating her. After all, if it turns out that she is not cheating, and she finds out that you were investigating her, that could sour the relationship just as easily as if she were having an affair - only in this case, you are the "bad guy" - the jealous, insecure, "nut-job" - and you will be the one your mutual friends turn against. So, choose carefully how you are going to go about things.

When you are completely sure that she's been cheating and you have proof, only then should you confront her. You also need to figure out what it is you want to try to do - rebuild the relationship or split up. It is critical that you keep your anger under control because violence or destructive behavior can result in legal trouble that will cause far more damage to your life than her infidelity did.

Ultimately, it is important to get your emotions under control and carefully evaluate whether the signs of a cheating wife that you are noticing are actual indicators of cheating, or something else, and then if cheating is taking place, what to do about it.
