Sorry you're here buddy. You've come to the right place though mate. I don't have much time to post anything but just wanted to touch base to support you and let you know I read your sitch and one of the veterans should be here soon to give you some feedback. I too suspect MLC in my sitch. Look to your wife's childhood for abuse, neglect and abandonment.
In the meatime, read Sandi's rules, read Ready to Changes quotes threads, then all the ones Cadet posted above. Come here for advice before responding to your wife or making big decisions. The people here are fantastic to help that way.
Chin up, and stay strong mate.
PS what MA do you practice?
