The last relationship I was in was with an NPD-type mythomaniac. What I regret the most was letting him take up so much real estate in my head. I also learned that my family is full of narcissists. And there is a connection there. There is a technique for dealing with these people, which is called 'grey rock'.

It's been 4 years since that relationship ended and it was at least 2 years I was in full blown recovery.

Focus on what you need to recover, what you can do for yourself. We only have one shot in this world. I think all young adults need to be taught to look out and avoid getting involved with people like this.
