Its a nice song. I could really relate because recently my bf cheats on me it he tolde he never ment to do it. I did have a hard time accepting his apology but in the end I just remebred all the good times we've had together! Anyway you never know if its about nick I mean I could be about that new guy, the older one I'm not totally sure but in the video sh was holding nicks dog tag(at least I think its his) so I'm pretty sure its about nick, but you nvr know, not unless uve herd it from miley herself!
