The 'keeps happening' part would be a significant problem for me. It would make me feel that my feelings didn't matter and T didn't really care about me. I'm really sorry this is happening with your T. Have you tried writing a letter and saying you really can't move past these feelings because the issue keeps happening?

I have had Ts make various mistakes a few times. Most did apologise and it never happened again. A genuine, heartful apology where the T was deeply attuned with my feelings, would be enough for me to let it go. But I couldn't if it kept happening.

I did have a T who became defensive about an issue. I let it go, but I never processed my feelings about it because her defensiveness was a major barrier for me. I need to feel my feelings are accepted and empathised with, in order to move on from an issue.
