People are here to either troll or get a voyeuristic or sadistic kick. If you don't reveal anything you wont get much attention. Remember this is a forum for (so-called) sociopaths and as such you wont get any help or therapy unless you have something to offer them in return.
It's more than likely that you will never know if your ex was a sociopath. There are some here that know their shit, however I'm not sure if there is anyone qualified to diagnose.
You'll more than likely just get exploited and played with (if you are genuine).
If you want people to help you analyse you ex, take your avatar down and spill the beans about your ex. Traumatic event and all. Then maybe, and only maybe then will you get any good discussion going.
You'll probably only get pics of dicks though.
