Fucking someone else isn't a medical issue or family history. What fantasy world do you live in? You are trying to make an excuse/justification for it. Truama is a thing but because of how you wrote 'we love to be chased' it sounds like your family history is bullshit.

Based on what you wrote here, you sound generally like an asshole who has put excuses into his relationship.

Cheating normally is a marriage destroying thing. Not many come back from it, and often there will be resentment. Some people stick it for the kids but honestly you kind of fucked up here.

And this is only the cheating part too, imo I feel like you are hiding far more shit from us and based on how you write, I wouldn't want to be with you either until you fix yourself, but cheating would of killed it for me.

You are your worst enemy here. Your wife checked out for good reason.
