You were more of a man that I would have been. I know Sandi and divorce busting isn't about blowing the affair out in the open, but I did that in my case.
Do you plan to tell his wife or family?
Sounds like he wanted you to do his dirtywork. He knows he pooped his pants, but he's not prepared to clean up the mess. I think OM having a conscious is very, very good thing for you. The OM in my relationship is supposedly a 'Christian', but had no issue destroying a Christian family by Facebooking my W, and then getting what he needed from my W, since his M is in divorce, and he was in multiple affairs. The crazy thing - my W still thinks this turd of a guy is awesome, and still loves him, and sticks up for him. She believes the OM's STBXW is all to blame.
Man, Nate, keep up working on yourself. Be there for the daughter. It sounds like you WW is about to really get a sniff and feel of the load she put in her pants months ago.
Keep us up-to-speed on your situation. I bet you have some updates for us this week!
