To me this song is about a girl that he was kind of 'paired up' with, in the sense that its that girl that if he wanted it he could have her pretty easily, and his parents 'love' her, but he thinks he doesn't. I think it has an ambiguous conclusion the "There's never been a knife that cuts me half as deep as you
and wide for you" could be referring that he fell in love with her, or can't stand her. I would assume the falling in love part because it makes more sense in the context of the song.
