i think i'm in love with my best friend

first off, i'm a girl and my best friend is a boy. we're both eighteen. we've been friends for 7 years and best friends for 5 years. we admitted romantic feelings towards each other when we were 14 but it was too awkward so i stopped it before it went anywhere. we didn't speak to each other for 3 or 4 months after that until a mutual friend forced us to hang out. we have never talked about it since, but haven't needed to. as we went to different colleges for alevels we kind of lost contact for a while and didn't meet up for a few months. however, as we've both finished our exams, we've started to meet up regularly again. seeing him again after all that time has kind of made me think that i like him more than a friend. we're going on holiday together (we booked it last minute a few weeks back) next week and i don't want thing to be awkward between us for it, so i don't really want to tell him just in case he doesn't reciprocate (and i'm pretty sure he only sees me as a friend) but i don't know what to do. should i just keep it to myself until my feelings go away? i'm not sure they will if i see him often. i'm going away to uni in sept whereas he's doing a foundation course in our hometown, so we won't see each other as much then, that's the only thing. helppp???
