Who are you kidding wc? Most of the folks here are trying to save their marriages. You come here and say "I want to be with OW but W won't let me" Boo hoo. You sound like a high school kid.
You have a problem all right. Its you!
#1. You cheated on your W.
#2. Your cheating with a married woman and want to be with her and keep flirting with her even after she said to cool it.
All you write about is your needs to be with her. What about your W's needs? She sure as hell does not need her H sticking it to another woman than coming home to her!

Are we supposed to feel sorry for you?
I have some advice, take it or leave it. Ask your W for foregiveness and than tell her you need a D. Than handle the fallout after that. Your a big boy. Than tell your LF to take a hike until you get your *&*^ together.

BTW, what is your mental anguish from? I see 2 selfish people with no regard of anyone else's feelings.
