Is it bad if I ask my recreational art teacher if he wants to get know each other outside of class?
I (33F) recent started doing oil painting as a hobby. The art teacher (43M) and I have really hit it off and things felt..flirty. My instructor definitely gives me more attention than others in the class, sharpens my pencils for me, grids my work, and even spent 15 minutes looking for a specific art book for me one day. We also laugh a lot and sometimes tease each other. He doesn't really do this with any other student; he usually VERY serious.
I decided I wanted something romantic to happen between us and picked out a rock and a seashell for him when I went to the beach, as a way to..move things forward (I am AuDHD and get the feeling he may also be neurodivergent.)
When I'm told my therapist this, she kind of freaked out and said if anything happened, it would be an "abuse of power", but I'm attending this class voluntarily, I don't get any credit/compensation/ reward for it, and I can leave whenever I want. I don't want to be a professional artist and I don't idolize him, so I'm a little lost on why she thinks anything romantically happening between us would be bad. She also said there's "no evidence" he's interested in me. (I might need a new therapist).
Anyway, I gave him the rock and seashell and told him why the rock reminds me of his art. He seemed to really like it and told me he collects rocks. But today during class he was super serious with me until the very end and then started asking me questions about where I'm from and things felt very nice/flirty again.
How crazy/inappropriate would it be for me to ask him if he would be open to getting to know each other outside of class??
TLDR - is it a bad idea to ask my recreational art teacher if he would be open to hanging out outside of class??
