They ignore you because they want to control you. One of the main reasons why a narcissist ignores you is that they want to control you. More likely, they want to regain control of you. A narcissist uses ignoring people as a way to punish them.
React with empathy and respect.
A narcissist thrives on conflict, and will take control of the conversation as soon as you get defensive or try to fight back. Instead, you can take control by making empathetic statements about the situation, which will help the narcissist calm down.
Breakups with narcissists don't always end the relationship. Many won't let you go, even when it's they who left the relationship, and even when they're with a new partner. They won't accept “no.” They hoover in an attempt to rekindle the relationship or stay friends after a breakup or divorce.
Although narcissists act superior, entitled and boastful, underneath their larger-than-life facade lies their greatest fear: That they are ordinary. For narcissists, attention is like oxygen. Narcissists believe only special people get attention.
"You're a bad person." "Nobody else will ever love you." "I'm the best you'll ever have." "Have fun being alone for the rest of your life."
They get jealous about everything
They talk a good game, but narcissists actually have very low self-esteem. Low self-worth/confidence/esteem is at the core of a narcissism. This low sense of self naturally makes it extremely easy for them to become jealous – very jealous.
A monumental weakness in the narcissist is the failure to look internally and flesh out what needs to be worked on. Then, of course, the next step is to spend time improving. The narcissist sabotages any possibility of looking deep within.
The narcissist uses ignoring you as a way to punish for some wrongdoing you committed. They don't feel the need to tell you what the wrongdoing was, they just jump into ignoring you as quick as possible to protect themselves from further narcissistic injury.
If there's one thing narcissists hate, it's being told what to do. When you push them into a situation where they have to answer to someone else, it's like their own personal hell. Figure out a way where you can get the narcissist in your life to be underneath an authority figure to really watch them squirm.
It comes hand-in-hand with this that narcissists hate being criticised or called out. Which is exactly why there's one word in particular narcissistic people cannot stand: "no".
There are many words people high in narcissism don't want to hear, but perhaps the worst involve a “no,” as in “No, you can't," "No, you're wrong," or — even worse — “No, I won't.” This makes it difficult to go about your ordinary business with the people in your life who don't understand the give-and-take of normal ...
Narcissists are frightened, fragile people.
Rejection, humiliation, and even the tiniest of defeats can shake them to their core. This leaves narcissists wholly focused on their image.
Type As can also be dangerous to narcissists
Although they can be targeted, type A people can also become a narcissist's worst nightmare. One of the most important defenses against dark personalities is having strong boundaries yourself, and type A people are usually aware they have the right to build them.
Grandiose sense of self-importance
Grandiosity is the defining characteristic of narcissism. More than just arrogance or vanity, grandiosity is an unrealistic sense of superiority. Narcissists believe they are unique or “special” and can only be understood by other special people.
They will often deploy a variety of narcissistic relationship patterns such as manipulation, charismatic, and exploitational tactics in order to ensure that their own needs and wants are met. As a spouse, you may be the subject of their manipulation and abuse, while your partner treats everyone else positively.
Unless they have had a lot of successful psychotherapy for their NPD, they do not feel guilt, shame, or self-doubt so long as their narcissistic defenses hold. This means that they do not think there is anything for them to regret, no matter how hurt you feel.
