Ok wtf do i do!!!!!!!!!!?

I like this girl. Donsnt like me back. She adores me as a friend. But thats all. She knows I like her. WTF do i do? How do I move on? or should I stay perhaps? i know everyone is going to say "just move on, find another gal" but im so infatuated by this women. I feel like it would be so hard to have feelings for another if I still know her. Do i leave her because its the best for me. Try and juggle being a friend and looking for someone else? Wait around? I just dont know. My feelings are all in a bundle. I dont want to leave her and I would do anything to have her but if its not meant to be then how do i stop.
