Ah, my posting the story was in fact not to show encouragement of loving a kaafir, rather showing that even if there may be the tiniest bit of unintentional love for one's family, that should not stop one from fulfilling Allah's commands. Not everyone is so strong, and for some it takes a longer time than others to stop loving a person you loved your whole life. It all has to do with how clean you nafs is and how in love you are with Allah. For some it takes their whole lives to reach that state. But Allah sees the efforts made, and will be pleased with them.
