Right basically eminem has had trouble finding love so he thinks he finds the perfect woman but in actuall fact, she is just like the rest of his ex's, A person aims at his love, gets it, everything goes on just fine, and a day comes when he is left abandoned, the love wasnt lust as it's mentioned in the song and so this short phase when the person had his love is etched in his memory forever, eminem brings out amazingly to all his listeners what it is like to be left alone when the person you adored from the core of your heart leaves you and you can't get him/her back at any cost.
