To me personaly, this song is about a guy who's in a relationship or something with a girl, but he feel's it's not right, he feels he made a mistake by getting involved with her, not because he doesn't like the girl, but he has doubts about himself and feels he made a mistake and now he has to find the courage and the words to tell the girl about his feelings, that it would never completely work out for them, he has to break the girls heart.
