Ive had a crush for 10yrs!!! Idk what to do anymore and all i want to do is get over it but i dont know how?

Allow to explain, I've had a crush for 10yrs. Times I looove the feeling this person doesn't know but the way this person acts when its just this person and I. So many things said and done that this person will never ever do to other friends, why? Cuz I've asked and everyone has told me they don't act like that around them. Lately there's been so much on my mind and somehow this person sneaks its way thru a thought in my brain. I dream of this person a lot. I'm not asking for a lifetime w/ this person but atleast a night full of passion. Idk if it will ever happen...as much as I would love to it can ruin many things. If we were to hook up noone would know cuz I aint telling I just want the satisfaction of being w/ this person for atleast a day!! Is that to much to ask for?? 10yrs crushing is crazzzy, I think this person crushed on me first and I never paid attention and now idk if this person is just only attracted to me and I'm the one who wound up w/ the feelings now. Its so complicated!!! How can I get over this person???? Help!
