Yesterday I got asked by a girl in many of my classes if I wanted to have coffee some time. I get along with her quite well and we have some good discussions about what we are studying.Unfortunately, I think she may like me in a more than friends kind of way (unfortunate because I have a girlfriend). My problem is I don't want to make the situation awkward and ruin what could be a good friendship and study buddy. Looking back, at the time I should of mention that I had a girlfriend and couldn't have coffee on a certain day or something. But now I feel if I mention my her while we are having coffee it will seem like I mislead her (not that I had lead her on) by accepting her invitation.Any suggestions will be appreciated.
