What should I do in your opinion?

So i've been in love with this guy all year and we've never talked before. It was love at first sight, I know it. When he got a girlfriend this year, I cried hysterically for ten minutes straight. Whenever I see him, I get erflies but I'm also sad inside because I know nothing will ever happen between us (he's waaay out of my league). And now he's "dating" this girl, but they're not boyfriend/girlfriend yet. I cried when I first found this out. I don't want to cry over him anymore and have my heart broken, but at the same time he makes me feel happy on the inside so I don't want to get over him. What should I do?
