I don't think I ever interpreted this song in the way that a lot of people have. I felt that it was about a relationship Conor or whoever the song is about was involved in. He loved the girl he was with, but hurt her, perhaps by cheating or just treating her bad in general. He loved her all along, but fucked himself and someone he cared about so much over. That is why he is an idiot, guilty, etc.
