Absolutely. I belong to a non cheating group. It's just seems completely unfathomable that it could happen. Most of us are in 15+ year relationships and are friends with everyone. It's not just a "the women are friends with the women, the men are friends with the men" situation. We got a blend of genders all participating in the same hobbies. There would be so much social cost to cheating it would be kind of insane.

Where I work though there's a decent amount of drama in that regard though and I have noticed that one common factor is that the relationships are atomized. They either keep their old friends going in and there's almost zero expectation of their partners integrating into each other's friendships or there's just this expectation that men and women are fundamentally different creatures. That whole men are from Mars women from Venus shtick. From the outside it seems like emotional distance where people look at each other like they aren't targets of empathy - more like they play by a book as if they can just put the right inputs in they will get the desired outputs.

I know this is entirely anedotal and that anybody could theoretically cheat for any number of reasons... It's just something that I noticed about the groups of cheats that I am aware of.
