This song to me means that love is a hard thing and he would do anything to get her back in his life. Also that he is at war with himself for the stuff he said or did to lose her. And when the hreat and sould thing come on he would do all that but he can't just give her his soul cause he allready sold it. Well in a past song from them is called sell our soul. So that's why she can't have his soul. And its very deep and when I heard this song I wanted to cry cause I was losing everything in my life. And it was depressed time. Now I'm doing better but hey who knows how ill come out.
