Barbara I guess I don't need to point out that if he is still in contact with OW then he really hasn't been trying, just going through the motions. Mine did the same thing, had an OW and went to MC with me. She told him as long as OW was in the picture he was skating and he really wasn't doing anything to make the R better. Go see the attorney, you don't have to do anything today. Just get an idea of what you can expect if things don't work out.
I'm so sorry you are here and in this situation. If it were me I would figure out what I wanted and what works for me and do it. He sounds like he is in the "fog" that people talk about when someone is in an A. Until he is able to gain some perspective about what he stands to lose vs. what if anything he will gain, there isn't much you can do. You can't control him, only you, so start doing things that are for and about you. Take care of yourself and be gentle with yourself, there is no set schedule or real rulebook... There are some really great people on these boards that will be your cheering section and be there for you.
