I have just decided to take out of session contact off the table in my therapy, because since I have started developing parental transference towards him, I'm finding email between sessions causes more problems than it helps.
I told him today and he said if I prefer, I can talk to him about what I would like in a response from him, but I said I don't know what I want from him, and I think it's better if I make this boundary and don't contact him.
He just said okay.
