i have a crush on someone but it hurts me so bad

Since tenth grade, during school orientation period, there was this one boy. I spent an entire year trying to friends or girlfriend by picking the same classes, trying to catch his eye, I constantly pestering his friends just to find out if he even knew I existed. Whenever I tried to talk or texted him, he always answered in the short nonchalant.

And then, in eleventh grade, everything shifted. He finally realized how much I liked him, but instead of actually talking to me, he just.... act normal.

I practically begged for a sliver of his time, asking him to go to the arcade or just hang out, and he’d give me that vague, answer ‘yeah, let’s do it someday.’ But that ‘someday’ never actually come. He’d find any excuse to run off to his friends the second I walked into the room, leaving me standing there feeling like a fool for trying so hard to win his heart.

He's a typical unpopular introvert weeb nerd that has a slim and short body who also wears glasses. He's not really have the handsome face features, but he has a sweet innocent smile and pretty cute face.

I like him a lot. I don't even care if i cant be his girlfriend. If i can be his friends, i would be so happy.

And lately i feel like a fool whenever he doesn't answer my message. His friend accidentally tell me a secret that he have a crush on someone but they never told me who is it. If he was gay, i wouldn't mind and probably just forget my feelings for him and keep trying to be his friends but if it was a girl.. i don't know how i feel about that, how can someone like him have a crush on someone when he also treated me bad..

what can i do to stop liking him?
