Hi there sportsfan. I feel for you. Yes, it sucks big time. I have a theory that it sucks in direct proportion to how much we have defined ourself by the relationship. So, I never had a life with I met my W and for 18 years she took the place of the personal growth that I needed. When she moved out, I was instantly transported back 18 years and a couple of times it took many pitchers of margaritas to endure the night. Now, I've grown to where her bad behavior doesn't determine whether I'm having a good day or not. Mostly
As hard as it sounds, all any of us can do is back off and GAL.
There's a good group here and they are a very valuable resource of inspiration and support.
