Sorry to 'double message' again, but i forgot to add one thing.
You mentioned that his sister said he is beginning to exclude her. Maybe have a coffee with her and try to get the low down.
Fight for your M, TTA. Make the opportunities happen. You've said that you are sure the man you married is buried inside. Find help. If a D does happen, move on. Until the final judgement comes through though (if it does), fight.
You've tried waiting. Didn't work. You've tried listening. Didn't work. Did you ever try using your gut to change the game? Yes. When you went to N.O., you came back to him wanting MC. So sometimes it helped, and sometimes not.
180s are about doing what works and changing what doesn't.
