Well here is how I would break it down. The singer in this song is reaching out to a girl who has decided to leave him. He is trying to understand why she has decided to leave him, because in his mind she will regret her decision (the regret...will start to show...you won't forget my name). He tries to blame it on her personality and then decides that maybe it was something he did to her. All in all he is very perplexed. I've been there, so I can relate to what he's trying to get at.
