How do you know your ex was a psychopath and heartless?

It would be nice to know even after the break-up wouldn't it. Seemed mine wanted someone to care for him without having much obligation on his own...he never failed to remind me of my roles while neglecting his. I don't know if he was a sociopath, or what.

As much as you need closure its not worth breaking your head trying to figure him out. If you allow yourself to get over him you will notice the change, when someone loses importance in our lives they become irrelevant.

Probably immature and thoughtless.
