Btw, he also had the option of breaking up with her before he started the negative behavior that led to the disintergration of their marriage and the resulting affair.

Now I'm calling you out on this one. The letter does not say he had negative behavior before the affair. It does not say their marriage disintegrated. It vaguely says there were "contributing situations." That's it. This is exactly what I'm talking about, you jumped to conclude that he somehow caused this. No, he didn't. Problems in a relationship do not result in sex with someone else. A cheater would like to think tha't's true but it isn't.
