Updated: July 29, Reader-Approved References. Worrying your wife is cheating is a terrible feeling, so you likely want to get to the truth fast. Pay special attention to her social habits, her behaviors at home, and changes in her appearance. Tip: Try to schedule a group outing with them so you can get to know them. You might discover that the relationship seems completely normal. On the other hand, if she refuses to make group plans or gets defensive, it could be a sign that something is going on. Warning: Keep in mind that these changes could have innocent explanations.

They're afraid.
Commitment is a slippery slope after all. Sometimes, wives just do things for no apparent reason to you. Imagine that. Sure, she can cheat on you in a physical sense. Sex is the biological imperative after all.
They have a self esteem problem, and they're seeking validation.
Not my wife. We think like MEN. We have a hard time thinking like women. When we think of cheating, we think of it as a guy. As guys, we are biologically programmed to be polygamous. We physically want lots of different women See: pornography, strip clubs, creepily staring at women, etc.
When a boyfriend cheated on me with a mutual "friend" years ago, I was sad, disappointed and furious with them both. It threw me into a tailspin of toxic thoughts, from pointless comparisons Does he find her more attractive? But one qu estion rose above the din, and looped like a drumbeat in my head in the weeks that followed: Why did he do it? Knowing the answer couldn't turn back the clock and make him un-cheat on me, but I did hope it would help give clarity to a situation I otherwise had no control over. As anyone who's ever been cheated on knows, learning that your spouse or significant other has strayed outside your relationship is a uniquely painful experience. In the midst of the teary talks and arguments that follow your discovery of the betrayal, you might never hear an actual reason or, as in the case of my then-boyfriend, they don't fully know the answer themselves. And you might not even see the signs.
