However, the following points are (perhaps less spoken of, but easier to objectively assess) indicators that the person may have Narcissistic Personality Disorder:
A recurrent history of TURBULENT interpersonal relationships. A narcissist does not value relationships like a neurotypical person does, instead they only use another person for their own addiction – narcissistic supply (admiration). Their sources of supply are endless, throughout their life they go from one person to the next only to escalate more drama.
If you look back at their history, there is a long list of people that they have been involved with. Independently if the attention is positive or negative, all this drama results in more attention. Their friendships are fake, rare and unequal and their relationship with their family is unloving and turbulent. So if in doubt, always look at a person’s history of relationships and how they value them.
Constant denial. ANY situations in the narcissist life are ALWAYS SOMEONE ELSE’S FAULT. When confronted by their victim, they will either:
Outright deny or use a common practise to blame the victim themselves, such as: “you provoked me to behave like this / you made this happen” OR blame it on something that they consider is “out of their control”
“I BEHAVED LIKE THAT BECAUSE I LOST MY TEMPER”
