Here lies the partner's salvation: if you, as his intimate, wish to sever your relationship with the narcissist, stop providing him with what he needs. Do not adore, admire, approve, applaud, or confirm anything he does or says. Disagree with his views belittle him, reduce him to size, compare him to others, tell him he is not unique, criticize him, give unsolicited advice, and offer him help. In short, deprive him of the grandiose and fantastic illusions, which holds his personality together.The narcissist is a delicately attuned piece of equipment. At the first sign of danger to his inflated False Self, he will quit and disappear on you.
