Gekko, I've heard of this happening but it's kind of a role-reversal with you two. Normally it's the man who is on his best behavior during dating and turns into a passive/aggressive sarcastic ahole after M. In your case it sounds like that's your W. I guess my first question to you is do you really want back into that M? It sounds miserable. No matter how hard you try she is just verbally tearing you down at every opportunity, and now according to friends and family she has ALWAYS been that way. I think the best you can hope for in recon is more of the same. Is that really what you want?
My advice would be to pull back, detach, get out and GAL. Leave her alone. She may want to recon down the road, but if she does I would demand she go through intensive IC and MC first.
You mentioned you have GAL activities, what are they?
