When I hear this I think of a girl repeatedly leaving or breaking up with him when a guy is in love with her and treating her right (I did everything right for somebody that does everything wrong). He keeps taking her back because he's deeply in love with her. And finally, she leaves him, and stays away for a while (Absence makes the heart grow fond, staying away from people). He gets his head together, and she comes back to him again. But this time it's different, and he can't answer her anymore.
