Thanks for all the feedback. Everyone that she has told (except her divorced friends and sister) are all on my side or trying to stay neutral. The whole sitch is incredibly unfair, but I can't focus on the injustice of it if I want to get myself to a better place. As for the agreement about sexual partners, that was specifically for after the divorce. I made it very clear that cheating was not okay. My struggle is that there isn't anything I can do to stop her if she started. I avoid the topic completely at the moment and focus on myself, the kids, or other interactions. I'm going to rethink cohabitating. It'll be terrible to not have the kids around as they are my rock, but like others have said, I'm not sure I could endure the kind of personal hell it would be to watch my wife move on.
