well there's this girl, let's call her "A".
from the first day i met her i knew i liked her, a lot, but i didn't know whether she was bi, gay or straight. I was always unsure because she would always talk about this guy she was in love with. But then she started doing stuff that really caught my attention. she would make up songs about me, she would unbutton my pea-coat and pull me in for a hug in my coat then she would button it back up to the neck stop run her hand across my face

stare at me then pull me in for another hug, or we would just stand there and i would look over and she would be staring at me. I don't know what to do i haven't really told anyone i like girls except one friend. And i'm afraid that i might be wrong about the signals and if i tell her how i feel it might just separate us a little. she went away to college so i want to tell her as soon as possible before someone else has their chance with her.
so should i tell her? should i first come out to her then tell her my feelings? should i just leave our friendship the way it is and not bring it up? any advice?
