I don't have any personal experience with this. (Presumably there will be other PC members who may have some coping tips they can share.)
In the meantime, here is a link to DocJohn's article on communication within relationships. And then, also, you mentioned your husband having been diagnosed as being on the Autism spectrum. I presume (hopefully not incorrectly) that he is considered to have Asperger's Syndrome? So, assuming that is the case, here are links to 6 additional articles, from PC's archives, on the subject of Aspie / NT relationships:
9 Steps to Better Communication Today
Romance, Love and Asperger Syndrome
Aspergers and Non-Aspie Relationships
