Thinking about moving to this cute boy

I think I’m crushing on this guy
This guy sits right at the back in history so I turn around to look at the door if someone’s there because in our school it makes a beep sound if someone is there so each time I turn he has a huge smile on his face. Another time I walked past him and he looked somewhere else the whole time and then yesterday he looked somewhere else too but this time he was trying to hide his smile
He has a girlfriend but she speaks crap about him everyday to me and says she just uses him. One day I saw her stroking his hands and holding them and when he saw me he let go of her hands 😭
He turned around and looked at me twice before leaving class and he once tried to leave at the same time as me. He made strong eye contact with me when we saw each other but then broke it after like 2 seconds.
I keep staring at him and he went and told a mutual friend about it and the mutual friend said oh apparently u keep glaring at him.
Does he like me

Doesn't matter if he likes you. He has a girlfriend. Don't mess up their relationship. If he's single, sure. But he's not.

Does it look like he does I won’t get with him it’s fine

but does it look like he likes me please answer with. Yes or no, I’m just confused. And it’s okay I won’t ask him out
