The best way to deal with a narcissistic mother-in-law is to "kill her with kindness." This method works on most people, by the way. Be as nice and polite as you can possibly be but don't engage her more than you absolutely have to. Remain calm and don't feed into her Narcissism and neediness.
Punch her in the vagina.
let him have his time with her but you stay away and dont allow him to abuse you
Celebrate !
Dump him
The most unwanted characters are those with a Narcissistic personality disorder, and the way to deal with them is to avoid them.
My mother suffered from (undiagnosed) Narcissistic Personality Disorder. During the last years of her life she showed signs of Dementia. My step-mother (my father knew how to pick his women!!) has been, for her entire life, a full blown narcissist with all the traits of Narcissistic Personality Disorder. She has recently (she is 78) been diagnosed with Vascular Dementia. I have no idea how to cope with it. It is soul destroying to have to deal with her.
Not unless you find a good therapist and get some help with those issues. Check with your local mental health association for professionals who deal with childhood trauma.
Get out of there! You can't change them, so I move on to more sane people.
Some do. It depends on how she has the family roles set up and where she's getting her narcissistic supply from.
There is nothing you can do if your in-laws like the ex-girlfriend/wife. They are friends and you need to respect that.
Yes. Narcissistic Mothers always do.
That's tough. You can try talking to her. But, most importantly you need to remember one thing, You married her son not her. Dealing with someone like that can be very frustrating. If your husband will not stand for you, you need to. Tell her how you feel.
