Very nice Si_07! Forced detachment is a very good way to do it!
PacLove, I even filed for D, and not my WW. I went through the same thing - is my M worth saving, why not just give up? I believe that it is part of the process. But you have to actually really give up on your M before you start working on yourself.
Imagine a life without her, cry like there's no tomorrow, cry again tomorrow. Move on, then move forward by yourself, with yourself.
Just cos things are going right, doesn't mean that they were always wrong.
