Help me ๐Ÿ™ƒ (Boys)

So there's this guy in my school who I am crushing on so hard that I hate him so much because of it, he's handsome, fit, same culture as me and other stuff. Anyway me and him met last year but we didn't talk that much because different year levels and I don't know, we just awkward but I kept catching him starring at me and we both just I don't know like crushing on each other and not doing anything about it. But he got himself a gf from a different school or something and they still dating and all and I obviously got sad and angry. But recently this year we have talk recently because I'm just nice and whatever and my friends saying he's still crushing on me because they caught him looking at me and all even though he have a gf still ๐Ÿ˜. I do not want to be a home wrecker or something but I'm trying to get over him and all but I just can't to let it go and I don't know, I just always feel like there is some thing between us. This is my first time liking a guy like him more than anyone else that I use to have a crush on. It's so weird to me. I need help. Should I do something about it or try to move on and get another guy or something??? โ˜น
