crushes

i recently and still do have a crush on this guy well at first it was a crush but then i fell in love with him. i barely know him is it weird that i have fallen in love with him? i might never see him again and everywhere i go i think i could see him maybe but i never do. i have tried contacting him but he doesn't respond, should i just move on? if i do move on how do i do it? he has set the bar so high for me i actually might never like or love anyone for a while now. what should i do? i also cry way too much over him. the only reason i am not close to him is because i was to shy to talk to him. how do i boost my confidence and act normal around boys also?
