Who knows any good songs for trying to get over a first love? [FYI I'm a girl]?

I'm sure I'm not the only person out there who does this- using music as therapy? I think we have all done it at one point. But I'm trying to get over my last ex. He and I dated for two months, but I was in love with him (and still am) for two years. He and I, it's kinda been rekindled lately- but I just have this dreadful feeling that if we do get back into our relationship again that I will be hurt- and hurt badly. And soon. I just need music to try to get over him. I like music by people like Boys Like Girls, Stereo Skyline, Rascal Flatts, Ke$ha... I like a lot of music. Just anything to help me get over him because no matter how hard I try I just can't seem to get over him. Thanks.
