@dumbwife,
Hmm...
I understand why some women don't want to leave their husbands after finding out about cheating, even though that's not something I've experienced myself.
I disagree that keeping a husband, no matter what it requires from you, is a healthy goal, however. Just in general. You seem to have done something that is working out for you, now anyway (I'm curious about whether you can keep this up long-term, but that's another story).
If a guy is a jerk and a cheater and requires THAT much subjugation of your personality and general bending over backwards to appease him, I think that in general the cheated-upon wife is better off without him.
However I'm not saying that cheating should always instantly terminate a relationship. I know people who have gotten through it in a healthy way. Usually with a lot of effort from both the cheater and the cheated-upon.
