The narcissist that did the most damage to my mental well being:
Was self centred - only ever talked about himself and how my plans should fit around him.
Switched from being Dr Jekyll to Mr Hyde. If things didn't go his way, he was extremely unpleasant.
Bullied me and called me names all under the guise of "just joking". If you made any joke at his expense then he'd be offended and then try to justify calling me another name.
Would give you the cold shoulder if you said no to anything but if that backfires, then does something else, usually unpleasant, to get your attention.
Threatened to take his own life as a way of getting my attention.
Relentlessly attention seeking. Negative attention was better than being ignored.
Manipulative and conniving.
Sneers at anything you've achieved and inflate their own achievements.
Puts others down to make him feel it look better.
Devoid of empathy and humanity.
Lacks emotional intelligence.
Lacks self respect and integrity.
After exposing all these traits, it was painfully transparent to me just how pathetic this being was. I never understood why I kept making excuses for this person.
