Confessions of a Sociopath

This is weird and depressing, but fascinating too:


She's a successful law professor and a Sunday school teacher, with a host of family and friends. But her interpersonal calculus centers on how to manipulate and outmaneuver the many people in her life. Welcome to a world of ruthless cost-benefit analysis, charm, and grandiosity.

..For as long as Lucy dated Cass, I kept him as my sidepiece: I would induce him to make and then break dates with her in favor of being with me. He knew I was using him to mess with her. When he started to feel pangs of conscience, I broke it off with him. I waited until he focused all his attention on Lucy, waited until she got her hopes up, then I called him again. I told him we were meant for each other and I was just testing him. 

Lucy made things worse for herself—she had no sense of keeping personal things private, particularly from people like me who could use the information against her.
