PhotoArtist, the therapy session does sound exhausting, but maybe in some ways it was actually kind of productive? He screamed and acted like a child and used every move in the manipulation handbook to try to guilt you into letting down your boundaries. He did this in the hope of getting his way, but maybe you can use this as a reminder of why you have set those boundaries? Imagine how much more exhausting this kind of behavior would be if there were no therapist there and he was back in your home indefinitely!
