Right now you have a marvelous opportunity to show your kids, and your W for that matter, how a man handles extreme adversity. You can handle this with class, honor, and dignity or you can open up a big ol' can of whoopass payback.
Unfortunately, I think you will use all your info and such to try and humiliate your W and "her girl". You will probably try to manipulate everything to your advantage. You are already talking about filing back in NC to get the biggest bang for your buck. It just reeks of payback.
I really hope you come to take a different avenue than that.
You tell us that you are "a nice guy". I don't think so. You haven't accepted responsibility for much and lay the lion's share of the blame at the feet of your W and "her girl".
Does it really matter if she has an OW or an OM? I wouldn't to me. You seem to have a real issue with it. Why is that? I am just curious.
Really, you have a great opportunity for your kids... I honestly hope you make the most of it.
