Your situation sounds so incredibly difficult. I think you are doing great to have the courage to look at the tough decisions ahead. Some of the major change that needs to happen here has to do with your W. and if she is not in that kind of a place, it could be good to consider how tenable it is for you. Tough call, but then the place you have been in is also very painful in another way. I just see you hurting so much and being exposed to some really unpleasant stuff. She is hurting and confused right now and it appears that this may continue for some time.
Thinking of you, Treeman. Take care of yourself today.
