After two years of therapy; I still don’t fully trust my therapist, should I leave?

I’m anxious creature and have difficulty in forming bond for many reasons, probably the technical term is anxious attachment style.

So my therapist remains the only person I share my feelings with. Initially it was just honest thing to do, I would just talk about the things happening in my brain without any filter as I knew it was a safe space. She has not changed her approach and is a great listener. But lately I’m observing that I’m not sharing many things with her which actually affect me. Mostly because I have doubts about her as a person. It’s not that I don’t trust her at all, but I feel like I should’ve been more comfortable with her after hundreds of hours of therapy with her. Is this time to leave?

I discussed this with her and she said it’s upto me, which isn’t much convincing either.
