Narcissism is a personality disorder that causes people to have an excessive need for admiration.
Narcissists love themselves, but they can also be very abusive and manipulative toward others.
Narcissists are extremely sensitive to any kind of criticism or disapproval, so they will try to hide their negative traits from others by pretending to be something that they're not.
This creates problems in relationships because the narcissist won't tell you how he really feels about you and what he really thinks about your relationship together.
This makes it difficult for him to open up about his feelings because he doesn't want you to find out his faults.
The only way a narcissist can learn how to stop being narcissistic is through therapy with a professional who specializes in treating people with this type of personality disorder.
In order for the narcissist's self-esteem issues to be treated, he must first admit that there is a problem and that he needs help fixing it! Once the narcissist admits these things, therapy can begin and he will begin working on healing himself from his narcissistic tendencies through therapy sessions over time.
