I'm so sorry for what you're going through. I am just at a loss sometimes when I hear some of these WAW stories, even though I almost was one. And some days I'm still not sure. But so many stories on this board of W's freaking out and going off to live somewhere when they don't have a prayer of making it financially, etc...and just coming and going and still acting half married. Well some of the WAH's seem to act half married too, just in other ways. I was prepared (in my mind) to live with nothing but a card table and a folding chair, as long as I could do whatever I wanted with the table and chair. I think I'd have rather gone on food stamps than deal with H. But I figured out I have to deal with H no matter what because of the kids.
Anyway...no great advice, sorry. Just a vote of support for ya.
I can't remember who I recommended this book to, but you might read Adult Children of Abusive Parents. Just to try to understand her better. I see signs of it. It's a short book.
