Long distance relationship issues, and like someone else
I have been dating my current girlfriend for about a year and it is pretty serious, although long distance. I am a graduate student and live 2 hours from her home. Aside from holidays, we get to spend about every other weekend together. 2 serious issues have recently come up, and I am not sure what to do about them.
For one, I've begun to have feelings for another girl. She is another student in my graduate program. I don't know her very well at all, but something about her really excites me. Its probably a combination of the fact that she is very good looking and seems very nice/fun too. I feel really bad about this, because I think I am "in love" with my current girlfriend, but I am not quite sure. My girlfriend is really sweet and has been very good to me, so I don't know why I would start to like someone else. It could be just a crush, but its serious enough that I am concerned about it.
I also am having major issues with the distance. I am in my early 20s, and have 1.5 years left of my graduate program. During that time, the distance between my girlfriend and I will not change. After I graduate, I will be taking a job in a different city than her, and if we want to stay together, she will have to move there. We have talked about this, and she agreed that she would. But the thought having a long distance relationship for another 1.5 years is killing me. I want a girlfriend that I can see everyday, not just see on a couple times a month. And asking someone to follow you to a new city is a really big deal. I don't know if I want to ask her to do that.
So I am considering breaking up with my girlfriend because of these issues. I don't want to break up because I don't want to hurt her, and also because, perhaps selfishly, I don't want to be single either. I would love any advice, insight, or recommendations on this problem. Thanks.
