I agree, too, with both of you. My codie mom complained and wrung her hands and cried and bitched for years. Did she leave my AF? No. He eventually left her (and even though she hated him you'd think he ripped her heart out and stomped on it).
I've spent so much of my life being angry at her for NOT leaving him. I remember yelling at her as a teenager that I'd go live in a cardboard box somewhere before I would let my children grow up in this environment. I'm not sure I'd go that far, now that I'm older, but I'd go pretty close. I'd do what I had to do to keep my children safe.
I haven't explored this forum much beyond this group. Perhaps I shouldn't. "You're doing your best" may be intended as supportive but really it almost sounds like enabling to a point.
Anyway, IWTH, I know you have a lot of anger about your upbringing. I do too. We're both still grappling with it. If those groups make you angry, just try to stay out of there. Hang out with us instead. We're cooler anyway.
