I really like this guy...?

i talk to him every night for usually around 2 hours and we just talk about life and i dont know like everything. but i am head over heels abut him and i dont know he doesnt really seem to be flirting from what i can tell. other than that i dont have any cles at school with him, but whenever i see him we usually stop and talk for a few minutes just between cles and stuff, but not for very long. i dont want to come right out and say that i like him for the fear of rejection, but im pretty sure he doesnt like anyone (if he does he hasn't mentioned them) and i know he doesnt have a girlfriend or anything. but what do i do? i like him soooo much i dont know what to do HELP ME!!!
