Told my therapist I’m bi and now I feel uncomfortable

I’ve been seeing my therapist for a few months now, mostly for anxiety issues. I opened up to her in my most recent session that I’m closeted bisexual. When I spoke to her about my feelings towards another woman (I’m also a woman), I felt a sense that she was enjoying the story.. too much. She was leaning in towards me (which she has never previously done) and smiling. After the session, I felt extremely vulnerable and uncomfortable and it has now been two weeks since the appointment, and I’m dreading seeing her again. I’m not sure what it is exactly, but I feel like her body language seemed like she was too interested in what I was saying? Am I overreacting? Should I continue seeing this therapist?
