I've been reading some stuff lately... differences between narcissism and autism. I wonder if I have been wrong all along... maybe he is autistic?

GoodTherapy | Narcissism or Asperger’s? How to Tell the Difference

At this juncture, I am curious if there may be something that I am missing. Maybe I am the jerk? He's never been diagnosed and don't even know that if I brought it up, if he would even be receptive to getting checked out.

One thing he said to me that did stick out (and made me feel like I was being used) was that he was not happy/sad about the fact that he was not going to experience the stability he was looking for. He never did mention that he feared losing me, our relationship, etc. It was about stability, staying in the same house, routine, etc. He told me I just have an itch to make drastic changes every 2-3 years. He has successfully navigated different careers in different countries. I'm confused.

Anyone else out there thought they were married to a narcissist that turned out to be autistic?
