Swift, who has dated stars including Joe Jonas and Twilight hunk Taylor Lautner, tells E! Online, "The person I wrote this song about deserves this. This is about a person who was incredible to me, just perfect to me in a relationship, and I was really careless with him... This is a song full of words I would say to him."
On the track, Swift sings, "You gave me all your love and all I gave you was goodbye. So this is me swallowing my pride. Standing in front of you saying I'm sorry for that night."
