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.Sam Vaknin

Cognitive insight (knowing something) is not like emotional insight (feeling something). It has no psychodynamic effects. It does not affect the narcissist's behavior patterns, or his interpersonal interactions - the products of well entrenched and rigid defense mechanisms.Sam Vaknin

[Abusers] blame the world - circumstances, other people - for their defeats, misfortune, misconduct, and failures. The abuser firmly believes that his life is swayed by currents and persons over which he has no influence whatsoever (he has an external locus of control). But there are even subtler variants of this psychological defense mechanism. Not infrequently an abuser will say: "I made a mistake because I am stupid", implying that his deficiencies and inadequacy are things he cannot help having and cannot change. This is also an alloplastic defense because it abrogates responsibility. Many abusers exclaim: "I misbehaved because I completely lost my temper." On the surface, this appears to be an autoplastic defense with the abuser assuming responsibility for his misconduct. But it could be interpreted as an alloplastic defense, depending on whether the abuser believes that he can control his temper. .Sam Vaknin
