So obviously, there's this girl. I think she is a very nice girl, and someone I possibly want to get to know better. She is in a lot of my classes, but there is this other guy who is also in a lot of her classes who she seems to have taken a liking to. She continually tells me this guy has a girlfriend, and I believe her but I just see her always around him, and I don't know what to think. Me and this girl spend a lot of time together too, so it isn't unbalanced at all. So in one of my classes where this girl and her 'guy friend' both are in, I sit to her left, and he sits to her right, and there is this very attractive girl to my left. I have begun talking more and more to this girl on my left, and I'm not sure the effect it is having on the girl I like, when she sees me talking to her. We still see each other a lot, but if I am indeed making her jealous, is this a good thing, or am I giving her the impression that I don't care as much about getting to know her anymore? I don't want to send the wrong signals. Any suggestions?
