My gf and I have been going out for about 3 months now, but recently Ive been thinking a lot about this other girl. The other girl and I are friends, not really what you would call close, but I have a sneaking suspicion that she likes me. We text and MSN quite often, but the weird thing is we hardly ever speak to each other even though I see her everyday as we have the same lectures. She hasnt exactly explicitly said anything concrete to the effect of "I like you", but I've put that down to our jokey-jokey, flirty-flirty teasing type banter. (We just constantly take the piss out of each other - would you call this flirting?)
Anyway, Ive told my gf that I think this girl likes me, and she was quite supportive; she asked me if I liked her, and I said an emphatic "no", so she just told me to tell her that I have a gf. But I havent, and Im finding that I dont neccessarily want to - I think I probably do like this other girl, even if its just a tiny bit. I havent cheated on my gf, but I really cant stop thinking about this other girl. But I still really like my gf, so am in two minds about what to do. It doesnt seem fair that Im not putting all my efforts into our relationship, but I really dont want to split up with my gf; she has some committment issues, so the fact that we are together is somewhat of a miracle, and if I were to break it off and pursue this other girl it would break her heart and put her off guys forever probably. And yet I constantly think of the other girl. Is this just a classic "grass is greener on the other side" senario? Should I just leave it? Its kinda hard, because we are all in the same classes, so its not like I can avoid her. Should I leave it or go for this other girl?
