I'm really sorry you've had this experience.

Your T seems to be decompensating from some mental illness. It is nothing to do with you. It's neither your fault, nor can you help him. You need to walk away, find a new T, and talk this through with your new T. Don't worry about making any other decisions just now. Any communication from your T is his illness talking, and you owe him nothing. It really is not even in his best interest, nor yours, to consider anything he has said.

Get help for yourself to get through this.
