Apparently, my ex had more of the traits of Narcisitic Personality Disorder:
5. Has a sense of entitlement
Translation: They expect automatic compliance with their wishes or especially favorable treatment, such as thinking that they should always be able to go first and that other people should stop whatever they're doing to do what the narcissists want, and may react with hurt or rage when these expectations are frustrated.
6. Selfishly takes advantage of others to achieve his own ends
Translation: Narcissists use other people to get what they want without caring about the cost to the other people.
7. Lacks empathy
Translation: They are unwilling to recognize or sympathize with other people's feelings and needs. They "tune out" when other people want to talk about their own problems.
In clinical terms, empathy is the ability to recognize and interpret other people's emotions. Lack of empathy may take two different directions: (a) accurate interpretation of others' emotions with no concern for others' distress, which is characteristic of psychopaths; and (b) the inability to recognize and accurately interpret other people's emotions, which is the NPD style. This second form of defective empathy may (rarely) go so far as alexithymia, or no words for emotions, and is found with psychosomatic illnesses, i.e., medical conditions in which emotion is experienced somatically rather than psychically. People with personality disorders don't have the normal body-ego identification and regard their bodies only instrumentally, i.e., as tools to use to get what they want, or, in bad states, as torture chambers that inflict on them meaningless suffering. Self-described narcissists who've written to me say that they are aware that their feelings are different from other people's, mostly that they feel less, both in strength and variety (and which the narcissists interpret as evidence of their own superiority); some narcissists report "numbness" and the inability to perceive meaning in other people's emotions.
8. Is often envious of others or believes that others are envious of him
Translation: No translation needed.
9. Shows arrogant, haughty, patronizing, or contemptuous behaviors or attitudes
Translation: They treat other people like dirt.
