i think this song is about how his heart has been broken so many times, he always seems to do something wrong in a relationship "clean up my mistakes". he doesn't mean to, but something always goes wrong. he really loves the girl, but knows it's for the best that they break up because he made a mistake that will never make things the same again between them. he broke her heart by doing something wrong in their relationship and now it's his turn for her to break up with him, leaving him with another broken heart.
