<human>: I met my friend about 2 years ago in college, we've been best friends ever since but never interested in each other (at least i think so because she is really cold on her emotions) 

During these 2 years ive had two girlfriends and some drunk hooks ups of which shes aware. As for her she hasnt had a boyfriend since i met her and i found out that last year she dated a guy briefly (she never told me this and i never knew the guy, someone else told me)

Im probably one of her few male friends of which she always seems to look after, she has taken care of me when i was extremely drunk and she has listened to all my rants about my ex gfs and the like, shes super sweet and nice to me but at the same time shes super cold in a way i dont know if shes interested in me or not other than friendship, if i approach she tries to back off and the like.

Lately ive been hanging out with her alot, texting, talking, going out for coffee, movies, etc.. (i currently dont have a gf) and ive started to fall for her.. 

Today im going to see her and of course i would like some advice on whether i should let her know my feelings (considering were good friends) and obviously if its adviced i tell her then how shoud i let her know how i feel and how to do it in the less awkwardly way; if she would like to become something more than just friends, like a relationship.. 

What would be the best way to ask this? (considering the friendship background) and also in a way that somehow doesnt ruin the friendship if she knows ive started to grow feelings for her and doesnt reciprocate because well i really enjoy her friendship too.

Sorry english isnt my first language.

Can you summarize the given text in a few sentences?
<bot>: ive started to fall for my best friend, should i let her know this? if so, how? or should i just forget about it and move on..
