Girl 'flirted' and asked for my number - but has boyfriend?

There's a girl I met at college a few weeks ago, and we really hit it off. There seemed to be great chemistry between us from the start. I was disappointed to hear that she has a boyfriend, however I still added her on Facebook as I'd like to keep in contact.

Since then we have seen each other in person (just in day to day routine, nothing like a date or anything) and before parting the last time she asked for my number and said we should keep in touch.

The problem I have is that my instinct says she likes me, but pretty much everything she's said or done could also be put down to being friendly when taken individually. I am thinking that especially as she has a boyfriend, it must just be the latter.

So, do you think I am misreading the signs and should forget about the possibility of a relationship?
