Okay, I'm done, at least done with this pitiful balancing act of trying to manage someone else's issues.
I emailed H and told him I will be staying elsewhere at night and coming home after he takes the kids to school. I'll be there with them all in the afternoons and evenings until the kids go to bed.
My best friend has left me a standing invitation to do this, back when he was drunk and raging all the time.
I have to get away from him.
I also told him I was asking him ONE LAST TIME to go to marriage counseling or a marriage weekend kind of thing. That if he said no, I would not ask again, and I would consider that to mean he is done trying.
