Dear Justme,
I agree with Ruh roh, I think it's important for a therapist to maintain boundaries and she does. You can't help but feel close because you have "spilled" some stuff to them that is quite personal. So confidentiality is of utmost importance and I also wouldn't want to explain my history again. I think of my therapist as a teacher. In school, after you graduate, you don't often revisit your teachers again. Graduating feels like a big celebratory step. I wouldn't want to be stuck in high school or college forever. I don't plan on going to my therapist forever either.
