Paco - I am forever in awe of the depth of your understanding both of yourself and your W but one thing in particular struck me from your last post:
"In light of W's claims that she no longer loves me and wants to move on, I feel discouraged and also want to move on."
Move on my man. You have to let her go. She has said she does not want to stay in the MR (right now) - is therapy not just prolonging both your pain. I can't remember if it was her idea or your idea to go into MC but if it was yours, then the decision to self reflect is being forced on her. Nothing hurts like being forced to look in a mirror you are not ready to look at yet. She will get there. Until she does, every action, every word, every emotion, will only reinforce her view that she does not want to be in the MR. If it was hers, well, it has been said here before, they do it so they can tick the box that says "I tried".
I am not as articulate as others here, so I will try and be simple. Somewhere out there is a woman who shares the depth of your soul and the fierceness of your intelligence. That woman may be your W. Right now it is not.
