More and more it seems to me, that she is just "pretending" to work on the marriage, so she has an excuse if you blow your lid. She needs an audience to show that you ended the marriage even though she is the one who is wayward. She needs to feel that she is the victim (and believe you me, that in her twisted logic she actually believes she is the victim here...).
She would benefit from a good thrashing, I can't believe it's a felony...
All joking aside, she does not respect you. I think (and I might be wrong, I have been known to be wrong in the past) that I would talk to her that leaving marital home and going partying with other people is not working on the marriage. And I would leave at that. After that actions will speak louder than words...
