Do I still have a chance to be with her? Advice? (More at description below)

THIS IS A LONG BUT INTERESTING READ

Okay, so me and this girl have been close friends for a while, I'm 18 and she is too but she's a 3rd yr. college students and I'm 2nd, with only 4 months gap. We are in the same dance squad and many people mistake us for being lovers because of the way we act with each other. She hugs and kisses practically everyone in the cheek no matter boy or girl, it's her thing, and she's very trusting. Although she does that, she is much more sweeter to me than anyone else, she called me once the only person who could keep her sane, with all the problems and school work she has (loads of school works). The real weird thing is that she has has a boyfriend though (they've been together for 3 years now). We tried to make things happen between us but it only lasted for around 3 months (I grew quite impatient as to why she hadn't broken up with her boyfriend yet and eventually I thought she might be using me, I was too stubborn at the time to realize she wasn't, so it didn't really last), she was still with her boyfriend at the time. Eventually after 4 months we forgave each other and we went back to being the close lover friends everyone knew. This time our dance squad went to a resort, and here is where my real question is pertaining about. We both slept on the same bed together (first time) with 1 other girl who was also a member of the squad already sleeping beside her. For some reason we had a problem sleeping and we both kept waking up for like around 30 minutes or so interval (the room was quite hot), we both knew this because we were sharing the same pillow. Eventually it came up to where she rested her head multiple times on my shoulder and she was the first one to place her fingers between mine while caressing it (I was too frightened to make a move on her but I knew I could and that she would allow it), eventually we fell asleep later that night holding hands together facing each other.

My question, what does that mean? Does she still like me and wants me to try hard to get her? Or is she just doing it to make me feel comfortable? Do I still have a chance considering the facts about her and what we did or do together? Did she possibly want to make love? What do you think? And any possible advice for the upcoming future? Tips for what to do next time when we sleep together again (what girls like us guys to do to them in bed like brush their hair back with their fingers, give them a kiss on the forehead, etc.)? Oh, and I'm too afraid to ask her if I still do have a chance with her, but I do know we still love each other very much, just not sure if that love is enough (better than her love for her boyfriend).

PS: Whenever someone asks her why she always hangs out and stays with me all the time but has a boyfriend, she dismisses the topic and keeps silent.
