This guy who has a girlfriend might be into me

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

Are you the same person I keep replying to OMG you got guy issues you a whole guy magnet

lol yes I’m desperate for more opinions PLEASE WAIT I HAE AN UPDATE.
I saw his girlfriend Today with her mom and we both didn’t smile at each other again. We have no beef but after these two dreams I’ve had we just don’t smile at each other no more (I obviously won’t cus I mean I kinda want her bf) lolll. But yeah so I wonder why…
Remember the other guy I made a thread about with the heart emojis and told me he likes someone else or something like that. Basically to make him jealous I sat next a group of boys in class and ended up talking a lot with one of them and exchanging socials in front of the other guy. So he asked me the guy who rejected me in front of the whole class saying ‘why are u sitting next to them come sit next to me let’s go’, I said no it’s okay u leave I want to sit here. He was annoyed and just sat behind me.
So me and this other guy be talking and talking and this other guy who rejected me texts me in class saying oh hey do u have a lesson after this even though he knows we don’t have a lesson because come on brev we always walk home after that last period 😂 dk why he did that.
But bro when he asked that question he was standing and I was obviously sitting
What do you think 😂 about both boys
