HJ.....I have no idea how my MR is going to turn out but if I have to go through this I am glad my W moved out and that we are separated. IMO, if you do it right there will be all the time and space both of you need. I have not seen my W since Sunday (for about 5 min) and have not had a conversation with her since Monday morning which was an email exchange about our D's basketball game.
Let me tell you......it is awesome! I am not chasing a thing nor taking table scraps. F that.
I think a lot of books or experts are not in favor of separation because you don't have a chance to communicate and work on the MR. I think those books and experts also assume that both parties are willing to work on the MR which in 99% of our situations that is not the case.
