This song to me was about a boy who treated her wrong by maybe cheating, or lying. And she dumped him and maybe he said something like "I dont need you" and left, a few weeks later, he comes back and wants her. He wants to cheat or lie again. So she writes this song to him saying that she does not want him back and he should get a life. I know this becuase I am accually going through this. Lifes a b*h. Then you die.
