Search Results: he's not into his crush anymore

I have an older brother (23) and I know my bestie from school always crushed on him, but I made it clear that he is not an option and he has a girlfriend. I ended up finding out that she had been skipping class and they had been screwing in my bedroom while I was at school for like two weeks before I caught them came home and caught them. I was so angry I never talked to her since (like almost a bit over a year now). I'm angry that my brother would even do it behind his gfs back, but way more angry and disgusted that my bff chose to tease and lure him into all this. I don't even think she's actually sorry for doing it and says it's not my place to have an opinion because it's controlling. I don't even know anymore.

So I have a crush on my physical therapist but they are not allowed to have relations with their clients. My PT is over soon, so I won't be his patient anymore, but he can't make a move on me since he is bound to the code of ethics. Even when I am not his patient, he would probably feel unprofessional doing so.

So, I have to make the move which would mean give him my number, or ask him if he wants to hangout sometime. I didn't follow him on instagram or anything like that bc I thought it was childish.
I am not sure if I should give him my number or ask him if he wants to hangout. I am nervous and getting cold feet about it. He is 1 year younger than me, and it seems he is into active/sporty girls, I am active and trying to get stronger, but I'm not like, an athlete.

I can feel that we have chemistry and I think he likes me, but he doesn't want to jeopardize his job and I get that. He always asks me what my weekend plans are, I think to see if I am dating or have a boyfriend which I don't. I don't know, it is very 50/50, I can't gauge his interest really.

Should I make the move?
