I feel for you man. I'm in a similar situation myself. Wife sayd the same thing to me. Wanted to separate. I dragged my feet a little and then confronted her last night saying that I disagree with the separation and that I wouldn't move out. If she felt the need to move out with D2 then that is her decision. Of course she flipped. Told me this AM she found a place and would be out on Monday. We had talked about MC, but who knows now. It was also our 5 year anniversary yesterday. Oh joy.
I guess, I'm just saying that I understand your pain. The advice seems to be not to smother her and give her space. It is counterintuitive to me and what I think is the reason we've drifted apart in the first place. But, people are saying it's the right thing to do. Even former WAWs. Trust me, I'm having the hardest time ever trying to detach from her. Good luck. FWIW, I can't believe she's still in the same bed with you. I would take that as a positive. It seems that if she really wanted the independence that she'd be sleeping alone.
