I think it would be up to your T to bring up anything you're supposed to know about CBT termination and after care, not you. It's his job, after all. I wonder if you're looking for a way to connect again, which is totally understandable. I've been through termination with Ts, and I know how awful it can be.

I don't think he would consider you a stalker if you contacted him to ask this question, though. Maybe you'd have to find another T if you needed more help, like a refresher course. Or, you could see a different kind of T if you need help with the termination itself.

It takes time to grieve the loss of a T, just like any other loss. I hope it gets easier for you.
