So I'm 2 years away from finishing school and I have a crush on a guy in my class. He came like 4 years ago and we didn't talk much, until next year when his seat was right behind mine, we talked a lot and we became a little bit closer, although our friendship was just during classes. That year I started to have a little bir of a crush on him, I don't know why but he just started to look pretty cute to me. Then the next year He was still in my class and I still had a crush on him but he was being kind of a d*** to me, but I still had a huge crush on him. And finally this year, he is still in my class and my feelings for him couldn't be any stronger but we don't even talk to each other now, eveytime he looks at me I feel like I'm melting and I start to blush, and I look away so he doesn't notice that I was staring at him (yes, I stare at him every class), when I see him shirtless at the pool I feel like I don't need anything else in the world, and when he talks to me nicely, I just wanna hug him and never let go of him.
I don't know what to do because I know that if I tell him how I feel he is gonna reject me and tell everyone, also if I tell my friends they are gonna tell everyone too and my life would be ruined anyways. Now I just want to be friends with him but we don't have anything in common, so I don't know what to do, pls help.
