Help me move on

I like this nerd guy but he doesn't like me back lol It's impossible to get over him as he's literally so smart and blah blah Please help I don't wanna keep liking him as I'm literally about to graduate high-school He's kinda my friend ig..but he's distant now idk why Maybe bc he wants to make me lose feelings? We were friends before I confessed btw but after confession and some awkward deep talks we kinda became best friends Now he's kinda distant Great guy though
