You've discussed this with her before, you say. So at this point she is just yanking your chain. She is deliberately disrespecting you. It's part of the abusive behavior this therapist has displayed towards you for a while now (she took away touch, right?).

Me, I would probably reach over, grab the phone, and hold on to it for the rest of the session. She tries to get it back, tell her you'll report her to the licensing board for physically attacking a patient. Not saying this is the best solution...

The best solution is to leave her. How is that process going?
