Semi shy guy is he kinda into me or do I need to back off?

There’s this guy I’ve had a crush on for a bit of time now, I met him via friends. I heard about him before I met him, that he was an overly serious good looking guy. At the time I met him I had a boyfriend so, I didn’t really think much of him besides the fact he was cute. my friend was surprised he was as talkative as he was with me off the bat but I felt he became a tad bit more reserved throughout the night after I mentioned my boyfriend in a topic (even though my friend argues he still came around often and found him doing a pinky promise move on me sus).

Fast forward to me being single (which I haven’t mentioned to most) and he’s still talkative yet I feel he doesn’t approach me in crowded rooms? When I talk to him he does reciprocate (even though I either get too shy and wonder off or he does the same) and if we’re both a bit drunk (I see him at parties) he leans in really close when we talk, hugs me, has even practically laid on me on a couch, and one time even pecked my knee because he spilt something on it. He’s sometimes left the parties at the same time as me/walked me to my car or driven with me to get food. Not big things, just little ones.

But I don't know, he’s also huggable with most people under the influence and also leans into convos. I also feel he’s more comfortable approaching other people to start conversations with. I know I’ve gone out of my way to make small talk, but I don’t want to come off strong or creepy. And I’ve only caught him staring a few times, not too many. I tell my friend maybe he’s into the other girls he approaches more, and hugs/leans into but she argues they’re just more aggressive than I am. Whatever that means. she stands by the fact he’s more hyped when I’m there but meh, I don’t think she knows him well enough. But yeah, u all think I’m over analyzing or should back off? though I never told the guy I have a thing for him! It’s been a while since I’ve been single so I don’t even know how this kinda stuff works anymore
