I really need help for this drama

Hey so I am Suzie currently in freashman year and I have some drama going on in my school. So their is this guy I like let's call him S and allegedly he likes this other girl M. So people in my school ship them like everyone and like yeah good for them except I remember ever since I have joined this school (7th grade) he has been staring at me and looking at me weird which could mean many different thing but he went out of his way to be jealous and to literally glare at the guy who I was speaking too. At one point S even tried to prevent me and the other guy from being in the same room.

But later on in 8th I thought he had stopped liking me. Except nope S started to stare at me even more. Same was for 9th Except I thought that this year since M is in the same language class as use I thought he would try to pull moves at her but he still stares at me even during language class even though literally everyone ships both of them (S and M). And since some ppl know that I like S, M's friends literally hate me.

So what should I do??
