Once, you identify a narcissist, you have to be on your guard. They are masters of manipulation. They can play with your trust and emotions as long as it pays for them. Don’t try to change them because they are not capable of seeing their faults. If you try to show them their faults they would have no qualms in labeling you crazy. Because of their lack of self-insight, even therapy can’t do anything for them. The only way to deal with a narcissist is not to have any expectations.
