A friend of mine just asked me to write something about affairs because she feels so betrayed. Its one of the few things at least I think it is that my husband did not do. Though post-divorce he hooked up with a married woman for nearly a year. But I hear from women all the time and the betrayal is overwhelming. You make good points. There are people who are going to cheat regardless whether it’s insecurity, narcissism, or a pattern from their family of origin and then there’s all those other cases especially those who stay in a marriage that’s not working too long and in those cases things get worse in a whole bunch of different ways.
