I need sad love songs about a boy(me) who loves a girl that doesn't want me.?

So here's a bit about my story, I'm in love with the most amazing girl, who loves me but doesn't think it's enough. She moved away during the summer, I'm in Washington still and she's in California, we still talk on the phone each night and text a lot but we rarely see each other via web cam. I've asked her to be mine a ton of times but she always evades my questions. We'll say I love you and everything I've sent her flowers and a gift for her birthday. But I need songs that are like this. Newer songs from about 2004 plus. '04 is when I met her and it means a lot since out 6 year is coming up soon.
