Dunno about that. Bob may get the idea that OP wants him too.

Maybe I'm looking at this the wrong way. Part of me thinks I should man up and go support her and be THAT boyfriend and be the better person.
She really is a good person and I don't question her integrity despite the extra-marital affairs. I have no room to judge there.
If his wife is hot, who knows what's possible.

But NO, Bob ain't going there with me. JS
