This song is definitely about a former love, but every time I hear it I think about it as HE broke up with the girl. He says "you've done no wrong." And he also calls her "selfless, cold and composed." Maybe it's just me, but it feels like she's trying to play off being dumped like she never cared. "I know you did." And it's hurting both of them even more. Anyone understand or agree?
