"Our therapeutic relationship was a roller coaster."

With the greatest of respect, you didn't have a therapeutic relationship, as in something professional, boundaries and healing. His behaviour towards you has been incredibly abusive and I'd be reporting him and seeking compensation of your fees through his malpractice insurance. I know the attachment is there, and you don't want to do anything that might jeopardise whatever you have left with him, I hope you are able to teach a point where you can complain about him though because his behaviour was appalling.
