September 26, 2017:
Pathological narcissist and sociopath. Those things fit perfectly.
Uses her considerable intelligence and overpowering charm to manipulate people to her desires, no matter how passing or trivial or impulsive. Lies ruthlessly without qualm. Her view is that this is simply reality: everyone behaves this way, so that if you don't you're being foolish, and you deserve whatever happens.
Told me what I wanted to hear. About soul mates and friendships that never end. When the reality was that in her radically sexist view that women and men are different species she believed it was impossible for people of different genders to be friends. So that I should have seen it coming.
She was the only person in my life with whom I didn't feel lonely. When she left I believed without question that I'd be lonely every moment the rest of my life.
