I want to break up with my current girlfriend. She has done nothing wrong, I just want to move on to something new. She is my first girlfriend, and we have been dating for almost 2 years. It's long-distance during the school year, but we talk and visit often. Our relationship is healthy and pretty much conflict-free.
I suggest talking to her about how you feel first. The way it looks, breaking up might not be your only option. You should try to branch out and have your own social life. You say that you are a huge hypocrite, but the way it sounds, it might be that you need to truly notice it to. I'm sorry if these words sound harsh, but even I at one point had to swallow my pride to accept the fact 100% completely.
Just say you can't handle the long distance thing anymore. You're at a point in your life where you want something more than the odd visit. Say that you love her, but you don't feel that your relationship has progressed much in the time that you've been together, and it's because of the distance.
Like >>2 says, you have other options than simply to break up. Even if you break up, you'll have the same problem during your next relationship (your girlfriend eating up your social life).
So I suggest that you discuss with your girlfriend about the time issue, that you would like more time for meeting people. It's important for your well being, she should accept it.
Thank you, everybody, for the advice. I still have not gathered the courage to talk to her about it. It's hard because in the summer we live near each other and thus hang out quite often, so I feel like I can't suddenly spring this upon her.
