As bad as it may seem at the moment, I would say to just break up for the time being. I`ve been there, done that, and it didn`t really end well.

Asking someone to wait for your dream is selfish if you TRULY care about them. Just make sure you are very clear as to why you want to end the relationship. Being away from someone for a year is going to put a huge amount of stress on her (but not you, really, as you`ll be in a different environment with other things to think about and little time to become depressed.)

If you come back in a year and you still feel strongly toward each other, there is going to be nothing to stop you from getting back together. In my case, I burned my bridges (so to speak) to avoid regretting things, but... I don`t think it was the wrong decision in the long run. The other party was able to get over it fairly quickly, and they were probably happier in the long run... And I was free to really think about the future without wondering if I`d be hurting them.
