Cover art for Downfall lyrics by Matchbox Twenty

It seems to be about someone who he wants to be with, and she knows it but for whatever reason she doens't want the relationship. However, even though he wants to be with her, he knows he won't be good for her ('be my saviour, and I'll be your downfall'). This is one of my favourites on More Than You Think You Are.
