sometimes persuading someone to stay doesnt look like a verbal request. Sometimes its changing tactic and being a bit more caring or subtly putting down other therapies or therapists or even double bluff "if you wanna go maybe you should" knowing that the other person wont and will stroke your ego to say how right you are.

But then also maybe you resolved things and he is good and strong. I simply dont know and view things through my own lens and twisted reality.
