^ xdude I find it a fascinating subject. I have been doing some of my own thinking on it, and reading though not sure how accurate the source is, just peoples opinions, but usually based on experience.
I was accused of being manipulative from when I was a child and I know then it was not intentional. Over time I have tried to observe myself and began to see it or acknowledge it. On my part I will say it occurs naturally. I dont have to think about it. I think the environment I grew up in felt very unsafe to me and I had to find any means to get my needs met. Whatever worked, for basic survival. I guess this worked. Over time with practice it got more embedded and maybe other healthier ways of comunucating or interacting did not have as much chance to develop. So that is my personal story. I want to say I dont use it for "evil" or sadistic purposes. Just to meet my own basic needs. And whenever I am aware or conscious of things I choose the healthier or "good" route to take in a situation. Exceptions might be if I am under a great deal of stress. Desperate times desperate measures they say.
I cant say how it is for others. I am guessing there is a spectrum. An aspd might intentionally deceive and manipulate to an extreme of causing a great amount of harm to others. Conscience is a mitigating factor no doubt in how much one abuses this. I would say BPD has the most conscience of the cluster b and malignant NPD the least but just an opinion.
So as for him I am still figuring him out. He has claimed all along he is an "empath." I have no idea if he really believes it or is playing on my emotions. Its like there are two extreme possibilities. 1. He is a well meaning sensitive empath and I am being irrationally paranoid. Or 2. He is running a con on me and manipulating me deliberately and my own sensitivity is making me easily mamipulated.
Two extreme versions of events and either can be true. Maybe its obvious to others on the outside but its not obvious to me. I am leaning towards the latter now (that hes conning me).
