When I saw them in concert Cris described it as being about "a friend that's always been there for you even when you screw them over". It makes sense, but not totally because it doesn't seem like the person is there anymore in this song.
My take is he screwed up, the other person ended the relationship, he realized he was wrong, is apologizing, hoping they will forgive him, but even if they don't, he wants them to know how important they were to him/how much they changed his life.
