Seems that happens on both sides! My ex-wife ran off to cheat with someone else, then divorced me so she could be with him. One day she had to flee with their son because he threw her to the ground and held a gun to her head threatening to kill her. (He was drunk, and it was common for him to get drunk and be abusive.) So she took off and said that was it, she would not put up with that kind of abuse. Then a couple months later she goes right back to him. She didn't leave me because of any kind of abuse at all. Despite being a Christian, she just got bored with me and went looking for something else. I think there is a lot of truth in that some women just tend to want to be with the "bad boy" types, maybe for the excitement of it, all the while just hoping it never gets out of hand. After enough time, she figured out I just wasn't going to be one of the "bad boys", so she went to find one and sticks with him.
