If you've read the entire twilight series, you'll understand what this song means. I won't spoil it. Promise =) If you compare it to the story, Edward always tells Bella to stay away from him because he's dangerous. Edward believes that he doesn't have a soul due to his immortality and always tells Bella that she's "got it all" as a human. As everybody knows, Bella wants to be a part of him. Edward is always fighting the urge to be with Bella saying "I ain't got no fight in me in thiw whole damn world", but fails although he may be strong physically and mentally. This song is a very impowering romantic song that displays Edward's unselfishness towards Bella, becaue he longs for her to live her life normally. Beautiful song, I'm currently head over heels with it!
