Help!!

I have a big problem. So there’s this boy in my class but he’s a year older then me because he was held back in kindergarten because he switched schools and I’m pretty sure that he’s a fuckboy. His best friend keeps telling me that he says that “he will fuck you one day” and he looks at my butt a lot. It doesn’t help that his best friend has a crush on me. But the problem is that I think that I’m falling for him and I know that I shouldn’t. Idk what to do
