I think it's about maybe a girl who showed him the world in a different way, but eventually it all becomes stressful and complicated and all he has left is her. Society is telling him that he shouldn't think differently, so he's saying "Maybe I'm thinking I should just keep To the things that I've been told" He's telling the listener that maybe he was wrong all along. Eventually towards the end of the song he says "You were the one Who helped me see You were the one You were the one Oh you gave it all to me" trying to say that he really was wrong and that he shouldn't be near her anymore because she makes him crazy
