I feel this song is about a relationship that the girl he was with took him for granted. Everything he did for her was treated like it wasn't anything special. I feel the guy decides he needs to leave because he he isn't being treated right for all the things he did for her. After he is gone, the girl realizes everything she did wrong and the reasons he left. That will make her love him so much more when she finds out all the things he did for her. It will make her hate him because he was so amazing, but he just walked out of the door on her. In the end, she is alone and sad and he won't be there.
