The exact cause of true narcissism has yet to be fully proven. Psychodynamic theories suggest the root cause is experiences in early life which cause the narcissist to create a flawless “false self”, which must then be “defended” throughout the individual’s lifetime. Narcissists are by definition inordinately self-absorbed individuals. One of the key personality traits of a narcissist is that they are virtually incapable of seeing things from another person’s perspective and are basically unable to express empathy to others.
"The important thing to remember is that narcissists do not think the way we do, nor experience the same emotions. They operate solely from ego, so the usual emotions of missing someone or feelings of sadness and regret typically don’t affect them. The narcissist has no real friends and only fake self-esteem. A narcissist is someone who never grew out of being a selfish child. They find it hard to share and even harder to share the limelight, always wanting to be the focus of attention."
The narcissist has a split personality after his public. Some narcissists are unlikable, flagrant egotists. Others can be charming, intelligent, caring-that is, until their guru-status is threatened. The narcissistic person is incapable of a high level of reciprocity and compromise. On the one hand it can be charming and attractive, on the other hand it can be manipulative and destructive. One thing you will soon come to learn is that “nothing is his fault”. I’m sorry! doesn’t exist. No way! Sadly, narcissists don’t have warning labels printed across their foreheads. That means you need to be aware of the red flags.The best way to manage a narcissist if you cannot leave the relationship is to not reinforce their narcissistic behaviors.
