Good luck man. Im not sure of what happend to start the divorce but your wife sounds alot like mine, searching for something. I got the I love you but not in love with you talk to. We are now divorced as of last week but remain close. I have been WAY kind to her, helping her thru alot of her problems but I think she has a long way to go. She is in the middle of a mid life thing and acts like a teenager 1/2 the time.
I have to start living for me and trying not to put all my thought into her and thats hard for me.
Good luck man your story sure keeps hope alive for me.
