I feel your pain. I struggle with resentment and wanting to work on M, too, all in the same breath sometimes. Sometimes the resentment seems to win.
You are strong, even though, you may not feel it right now. I have read your thread for awhile now and know you are. The hard part is keeping these feelings inside and pretending it is okay. But remember to focus on YOU and what makes you happy. Do stuff for JV. I have decided to do that, to just not worry about my H. I can't make him want to be with me or the family. But, I will be there for my kids. He is the one losing out. Sorry for the rambling. Just my two cents worth. Sherry
