There are four techniques of coping with a narcissist, whether male or female.
(1b) Mirror His Behavior
Mirror the narcissist�s actions and repeat his words.
If, for instance, he is having a rage attack � rage back. If he threatens � threaten back and credibly try to use the same language and content. If he leaves the house � leave it as well, disappear on him. If he is suspicious � act suspicious. Be critical, denigrating, humiliating, go down to his level.
(1c) Frighten Him
Identify the vulnerabilities and susceptibilities of the narcissist and strike repeated, escalating blows at them.
If a narcissist has a secret or something he wishes to conceal � use your knowledge of it to threaten him. Drop cryptic hints that there are mysterious witnesses to the events and recently revealed evidence. Do it cleverly, noncommittally, gradually, in an escalating manner.
Let his imagination do the rest. You don't have to do much except utter a vague reference, make an ominous allusion, delineate a possible turn of events.
Needless to add that all these activities have to be pursued legally, preferably through the good services of law offices and in broad daylight. If done in the wrong way � they might constitute extortion or blackmail, harassment and a host of other criminal offences.
(1d) Lure Him
Offer him continued Narcissistic Supply. You can make a narcissist do anything by offering, withholding, or threatening to withhold Narcissistic Supply (adulation, admiration, attention, sex, awe, subservience, etc.).
(1e) Play on his Fear of Abandonment
If nothing else works, explicitly threaten to abandon him.
You can condition the threat ("If you don't do something or if you do it � I will desert you").
The narcissists perceives the following as threats of abandonment, even if they are not meant as such:
Confrontation, fundamental disagreement, and protracted criticism When completely ignored When you insist on respect for your boundaries, needs, emotions, choices, preferences When you retaliate (for instance, shout back at him).
Before I got to your specific situation my answer was going to be the general one of Yes so long as you are willing to have no mind of your own, do all her bidding, praise her all the time....and even that might not be enuf.
Now that I have read your situation my response is different.
Your kids are 17 and 19. Why are they staying in that living situation? Why aren't they living with you? Why don't they have the gumption to function at another junction?
