<human>: There's this girl [A] who I was friends with way back and we ended up going to the same college. Long story short, she ended up liking me and we hung out once. She brought her friend [B] who is also her roommate. Through various friends, I found out that A really likes me.

I don't like A but I was really interested in her friend, Girl B. B is really shy around me but pretty fun when she's with her friends. I don't really know B very well but have been trying to use my friendship with A to get closer with B.

I don't know what to do about A. She is my friend so I don't want to hurt her but I don't want to lead her on either. I also want to get to know B better but since A and B are very good friends, would I even have a chance?

Can you summarize the given text in a few sentences?
<bot>: A girl likes me but I like her friend. How do I let A down easy and do I even have a chance with her friend?
