Ok, I've been dating the same girl for almost 3 1/2 years now, since high school basically. Freshman year of college (We go to the same school) my GF meets an old friend of hers. This girl is pretty much a knockout, so is my GF. We've been hanging out during summers mostly and going to parties and stuff during the year, all 3 of us that is. Well throughout this period of time, I've kind of grown to have a thing for my GF's friend. I mean, we're pretty much friends too, but I feel it has grown to be more. But the thing is, I don't know if this girl has been getting the same vibe I've been getting, and on top of it all, I don't want to hurt my current GF because I really do care for her and all. My question is though, what would you do about this? Do you think it's just a little phase for me? I really think about this all the time.
