With all the different red flags that women throw up, it’s impossible to make a comprehensive list. However, one thing stands out as an automatic disqualifier for anything but the most debased relationship. If she cheated on an ex, that should tell you everything you need to know. How a man can take any woman like this seriously is beyond me. Once that kind of betrayal is already in her history, the burden is on her to prove she’s somehow different now, and most of the time she won’t.

A guy will tell himself, “she was cheating on her last boyfriend with me so it’s ok.” No it’s not. Stick a fork in her, she’s done. She is not wifey material. Some men try to dress it up as chemistry or bad timing, but that’s just cowardice with a nicer label. If she’ll do it to him, she’ll do it to you when the situation changes, and that’s not a risk worth pretending to ignore.

Someone is going to get all butt-hurt and say that everyone deserves a second chance. Ok, maybe that’s true. For any man reading this, ask yourself if she deserves that second chance with you. Sure, she deserves a second chance, but do you deserve to be the one who gives it to her? The real issue isn’t whether forgiveness exists in the abstract, it’s whether you should volunteer to become the next lesson.

Are you such a scum bag that you deserve to be the one who gives a whore a second, third or fourteenth chance? Family and marriage law are already far too biased against men. Add a wife with a track record of infidelity to that mix and you’re asking to get screwed. You’re better off alone. A bad woman can cost you far more than loneliness ever will, and that’s exactly why walking away is often the smartest move.
