I am still confused. You said you two discussed and mutually agreed that therapy needs to be terminated. But then you said you don’t understand why he didn’t tell you he is terminating you. These are two contradicting perceptions of the same situation.

Do you have a new therapist? I’d try to forget about “friendship” situation. Previously trying to be friends with therapists or doctors resulted in very bad situations for you including unfortunate legal actions. Just keep seeing current therapist/pdoc. You should also discuss with your pdoc what happened with t (how termination took place etc) as he could shed some light and help you to move on
