this song means that when he met her everything was exactly how he wanted. she was perfect for him. But he had gotten to know the hidden side of her. he misses the way she used to be and gets sick of how she is now and thinks of how he loved being with her and he sees how she used to treat him and there's something telling him that there's something wrong. there are times when she acts the way he loved and tries to take advantage of every moment like that. he gets so tired of dealing with the changing back and forth, and he needs her even for what she is.
