This therapist had absolutely no business telling you that she might move away in 6-12 months to begin with, imo. If your t had any common therapist sense at all, she would know how distressing that news would be for some clients. Now she's engaged you in her limbo for several months. Will she stay or will she go? That was a totally bad judgement call on her part.

Your t told you something threatening. How she doesn't get that is disturbing to me. She should have been more logically prepared for your reaction and prepared to discuss. Instead, she shut you down. In no way would I apologize.

I understand t's make mistakes like anyone else. Under normal circumstances, I would think and hope this could be worked out. Often times, a rupture-repair can lead to a more solid relationship between client and therapist. However, you are now challenged with not knowing if this t will even be around in 6 months, 9 months, or 12 months. Is that insecurity going to loom in your head for all of that time?

I probably wouldn't bother continuing to see this therapist, but that's me. My need for a therapist will probably expand beyond 6 months to a year. To know that my t might move away in 6-12 months would be too unsettling, which would compromise the therapy. I might go for a session or two for closure, if I needed it, and that's it.
