Narcissism
The Mayo Clinic research group defines narcissistic personality disorder as “a mental disorder in which people have an inflated sense of their own importance and a deep need for admiration." Narcissism is often marked by a lack of true intimacy in relationship.Signs of narcissism may include (and are not limited to) superiority complex, grandiose self-image, entitlement, conceit, boundary violations, false charm, the Don Juan syndrome, manipulation, irresponsibility, rule breaking, extreme selfishness, negative emotions, and contempt towards others. Significantly, research indicates that high narcissism is correlated with susceptibility to infidelity.
