I was married to a guy for 33 years who was very similar to what you are describing. There was absolutely no emotional connection & communication was difficult...he would argue even when we were saying the same thing. There were times when I felt like I was speaking in a foreign language & his facial expressions never matched the situation.

It wasn't until after I left & moved far away & was talking to my new therapist that he suggested the possibility that I might have been dealing with a H who has Asperger's (ASD). The more I researched it the more it seemed to describe all my experiences with him.....it really helped me to have a better understanding
