Did he actually say "mature"? If so, I don't like his wording. Implying you're "immature" is definitely not okay.

It's one thing to sob on the phone and say "you're a stupid poopie head!", but your decision was not immature or based on immature feelings.

Regardless, I think he does mean well when he says he wants to talk to you before you take a break with him. I can't tell you whether or not he's trying to lure you in to continuing therapy because I don't know him, but I think if you do go to that appointment that you're of sound mind to determine whether or not he wants to lure you in.

Has he tried to lure you in before?
