I've posted about the basic overview of ASPD/Sociopaths here and here and a checklist you can use to somewhat identify if you think are one or might know one.
But the truth is that all of this will never fully explain an S to you. Every S has certain qualities that help to define them as an S, but not every one will add up. Most things don;t really add up with an S anyway. You never know who you're getting from day to day anyway.
I know my dear S very well because I have studied him intensely. My S isn't violent, nor has my S ever tried to scam me out of money. That's not to say that he hasn't used me for purposes of covering up who he is to his family and his boss, but no monetary gain ever came from a relationship with me.
If you have been in a relationship with an S who did take you for all your money or left you high and dry with a bunch of credit card bills, I do feel bad for you...and hopefully you were really duped by your S and you didn't just freely offer up the info.
My sweet S has however used my weaknesses against me, not that I minded. I am well aware of my weaknesses and they aren't even that bad. I need to be told that I am loved and cherished. I need that attention. Other than that, I don't require much from the person I love. I don't need the gifts or the acts of service, I just need to be told that you love me and you are happy to be with me. I don't have kids, I don't have a ton of debt. I'm very loving, caring and generous. I'm attractive, in shape and a dang good woman.
But, back to my weakness, my dear S knew this is what I needed, so he provided it to me when it suited him and he took it away when it suited him to do so or when he was in the process of "training" me.
I guess what I am trying to say is that your S is different than my S. You can;t compare the two, and reading about all of the escapades of another person's S will only further take you into a black hole of depression because you will start assuming that your S did all the things their S did.
Be smarter than that. Either accept your S for who they are...or move on. It's really that easy.
