It's hard to accept...but he's likely not the same person in real life. If you were friends with him, it might be totally different. You'd have to experience when he's cranky, deal with his problems, realize he's not the perfect person he might seem to you in the therapy room. And it could change in your head how you saw therapy with him. It could undo things you've done. There are reasons that ethical rules delay friendship by at least 2 years after termination. My ex-T was a social worker (LCSW), and she said she could never be friends with her clients, even if it had been 20 years. The rules are there to protect clients. Again, I know it's really hard...
