Do I stay or do I go?

[MrBond]

Go.

Not saying that you give up on your M, but if he's out letting his d*ck do the talking, then there's nothing you can do to control him. Go out and have fun yourself. Hang out with friends and start posting those on FB.

I agree that the OW is not your friend. Funny how she seems so understanding about how you feel, but is still sleeping with your H. Talk about messed up. Don't talk to her any more.

Start living your life.
