I have Asperger's. I'm also in a relationship with my wife of thirty years. Since we don't always see ourselves as clearly as others do, let me ask you: Did you see narcissistic behavior, thoughts of beliefs present in my recent post about compatibility?

That doesn't answer your question about whether they are similar. They might be but I'm not necessarily a good person to ask. My mother was a narcissist and I'm loath to think we share those qualities. That loathing might not allow me to be as objective as I need to be to give you a good answer.
