My advice to you is to immediately stop engaging in "unconditional love". Narcissists sense blood where others see only love and altruism. If �?for masochistic reasons, which are beyond me �?you still wish to engage this young person, my chief advice to you would be to condition your love. Sign a contract with him: you want my adoration, admiration, approval, warmth, you want my home and money available to you as an insurance policy? If you do �?these are my conditions. And if he says that he doesn't want to have anything to do with you anymore �?count your blessings and let go. Omar al-Khayyam, the famous Persian poet once wrote: when you want to have the bird �?set it free.
