Idk what to do 😩

So there’s this guy in one of my classes at school he’s like crazy over me. He likes me so much his whole family basically knows about me. The thing is I’m a senior and he’s a sophomore. May not seem like much but it is for someone who’s used to dating older guys that are 19 or 20. I like him and kinda wanna date him but with me being about to graduate and I’ll have all these college boys. I don’t wanna break his heart. I need advice from someone different cause I’m tired of hearing the same stuff from everyone else. What do I do 😩
