Cover art for Disillusion lyrics by Badly Drawn Boy

I was thinking this song was about a girl having high ambitions for her future and he feels like he's bringing her down. She wants the perfect person and a perfect life, and he's not part of it. He says "I didn't mean to fall in love" because he knows that he's not that perfect guy that she believes that she'll find. That's just me though.
