i think this song is about the new boyfriend of a girl talking to the her old boyfriend, who has realised that maybe he still has feelings for her, and it's coming in between the new relationship. absolutely beautiful. "and if you've felt her loyalty, what can you do?" -> i love this line, because it's not denying the past, but recognizing the helplessness of trying to move on.
