How to have someone NOT have a crush on you?

This kid in my French class had crush on me and it was quite awkward cause he sat right behind me. But he never actually told that himself. He indirectly told my friends, but he got over it now. He has a girlfriend now. Maybe if tu get a boyfriend, ignore him, pretend tu don't hear him, walk in the other direction. Plenty of things get creative :)

Punching him in the face would probably work.

Did tu tell him tu don't like him? If tu have just try and ignore him and continue declining him, middle school crushes don't last long.

A friend of mine is in EXACTLY the same situation. She has feelings for some one else though (two different people, actually, one after the other) and its kinda obvious so he doesn't ask her anymore. So, I guess tu could try to mostrar preference to other guys.
