You are, of course, right on. I struggle with it daily. I have set boundaries and I do call her on them. Monday night for example. She came home at 1:30am. I told her it was not acceptable. She didn't call, txt, anything. I didn't ask who she was with or anything like that. And, yeah, she flew off the handle! That is when I told her again that she needed to leave.
I am done being her door mat. Yes, I try to watch what I say or do and don't do anything to try to make her mad. If she wants to be pissy, she will find something to be pissy about.
It's all just so much B.S.!! I act "as if", I validate when she does talk, and I don't force her to talk if she doesn't want to. She changes from second to second and I am being even keeled and "happy" when she is in one of her moods.
Last night was decent. We talked and even laughed a little bit. We put the kids in bed and watched Lost. When it was over, I told her I was going in the shed to work on a trailer I am building and would be in in a little while. I got no response and just went on my way. NBD.
I know I have to have more dire consequences for her to face, but short of leaving, what would they be?
