i got this friend, not really know her a huge amount of time, probably about 2 months, i initially became friends with her twin sister more than her, and got on really well straight away, but i think i was a sholder to lean on as she was having some problems, now im pretty good friends with the other one, and i am definetly atracted to her.

we get on really well and she'll tells me everything, she happy sleeping in the same bed with me and getting changed infront of me, and im very open with her. i have a feeling that i could possibly have fallen in to this friends bracket. from what she's told me she generally goes for "bad boys", im would not describe myself as this.

well new years is coming up, i think me and her are going to the city where i go to university for a night out, it will just be me and her, im just not sure how i should make the next move to find out if she likes me or a way to get her to like me more than friends.

hmm seems like you're in the friend zone...however you still may have a chance. Do some flirting, kino, etc...and see where it goes. In the mean time, go find some other HB's to get her off your mind!
