Search Results: getting a girl's number

So these things happened all over the course of a few months. My ex boyfriend (we'll call him E) has a friend, well call him X. They haven't been friends for very long, but I want to say I'm not trying to DO anything with X.
One of the first times we hung out as a group X hugged me and asked me what perfume I was wearing, and said he'd buy it for a girl he'd potentially like. he's told me I look cute more than once. Every time he sees me he ends up standing or sitting close to me. E even pointed it out once. He hugs me everytime he sees me, but he hugs everyone. X has laid his head down on my lap a few times, when I was laying on my friends bed X would lean on my legs to prop himself up. I laid on his lap once back but it resulted in a accidental nip slip. He touches me a lot, like brushing my arm or hand, and resting on my legs, getting thing out of my hair, once I had something on my inner thigh and he brushed it off. He bought me drinks for my bday a while back, I remember that night he was tipsy and gave me a long hug. He asked for my number multiple times. X would tease me scrolling my phone to make me lose my place, or bothering me until I say the magic word. He's called me "good weird" before. Also sometimes in a group he'll end up just talking to me. E has said that he thinks X is into me because he always asks about me. E has said this exactly "if I were insecure the things he does with you would upset me". E has said once before that X treats me differently than other girls he's seen him around. X always talks about other girls he's into. And on social media he's shown me girls he likes, but they do resemble me a lot. I'm not sure if that's on purpose. X recently got a new girlfriend, I haven't met her but she lives like 2 hours away. I saw X like 2 days ago and even though he has a girlfriend now he still did all those things. Like touching/laying on me, getting things out of my hair and he randomly started taking pictures of me.

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?
