I'm sorry for what's been happening and for how you're feeling!
I want to clobber him for what he's doing

It seems he wanted to change his phone call boundaries and tried to do it gradually instead of being gently firm and just making the change he wanted right out. That's about him and his inability to be effective or his discomfort with boundaries. You said once before he needs to get his act together and reading your post makes me agree.
Please don't give up on therapy because of him. If you have to make a change, do that, but stick with therapy for you sweetie!
Reading what you're going through makes me feel so sad for you and brings tears to my eyes.
Keep talking to us, okay?
