From an aspie/socio(?) relationship story from a reader:
She told me how she also was incapable of empathy and that she often fantasized about violently murdering people, and craving power. She told me that to fit in she just moulded herself to whatever she thought other people wanted, and she didn't want a boyfriend because she could not be herself around such a person and it would invade her personal time (I had noticed the inconsistency too, I suspect she has many reasons). So in this discussion I became intensely interested in her, because although I have asperger's I find other aspies terribly annoying, and this was someone who did not have empathy faculties that I actually liked and during the conversation she changed her mind and decided she actually did want to be in a relationship with me, I still don't know why. Did she enjoy the power she felt over me when I was being affectionate, did she want the power trip from when I was dumped again 2 days later?
Anyway a short time later, we watched some movies together. She was really affectionate physically and I noticed the incongruence with how she described herself, but why would anyone lie about that? I wanted her to be 'natural' around me but ignored the inconsistency, as the person she was projecting was seemed so perfect for me. Later on we were messing around and ended up having sex and when we finished after I went to clean up she told me her mother was coming home for lunch and that I should leave. When I got home I found another message that said "you pushed me too far, don't try to contact me again." It occurred to me she was lying about her mother and it was so odd that she never once said "let's not do this" or "no I don't want to have sex" she even got the condom out herself.
I am pretty convinced she was a sociopath at least to some extent, I suspect she lies pathologically and enjoyed breaking up with me repeatedly for the power. I feel like an idiot falling for it a second time knowing she was probably acting, but the person she projected was exactly what I wanted in a girlfriend. Looking into it later, if I was right about her being a sociopath, it could have ended a lot worse. So I guess I am lucky to have it end with only some personal resentment and another ex to add to the list of people who I have seen naked but don't talk to.
