I found an article and it so precisely summarised how I experience our marriage, despite dh being a perfectly nice man and great father, I thought it might help others:
"When a neurotypical woman is married to a man who has the behaviors associated with autism spectrum (ASD), several things typically occur. Over the course of her marriage, she experiences herself as gradually disappearing. In the place of her former self emerges a person she barely recognizes. She is so lonely. So hurt. So … angry. She feels isolated, as her social connections have gradually diminished. She feels misunderstood by everyone who knows her, so she has learned not to talk about her “problems.” She starts to feels crazy. She also feels guilty, because her husband is a good man.
What has happened to these women? It’s difficult to see the process while it is going on, just as it is difficult to see the effects of water drops on granite minute by minute. But changes that are negligible day to day are incontrovertible over the long term. With time, granite that once held the characteristics of a unique natural form is visibly reduced to a smooth, monolithic surface.
Instead of drops of water, women married to men on the spectrum are struck by pain from unrelenting moments of being reflected inaccurately in the place they look most often for reassurance: the eyes of their husbands. And over time, they begin to interpret what is reflected to them as a reliable representation. They try to alter their own perspective, their own aspirations, their hopes and dreams, to bring them into line so they are consistent with the way their husbands treat them. The lonely process of love and guilt and shame rips them apart.
It starts like this: a man on the spectrum (most often undiagnosed) marries a woman for all the qualities he admires, but once the wedding is over, those very qualities become the things that spark the most unsettling experiences for him. She is outgoing socially, has interesting things to talk about, and is engaged in intriguing professional activities. She is well-regarded, confident, and kind.
For her part, she finds his thoughtful attention and his stability comforting. She is also drawn to what she takes to be his reticence. She admires his ability to maintain his focus so intently and to be so successful in his work.
To a man on the spectrum, however, living with a person who has these qualities may be predictably uncomfortable. Where he seeks equilibrium in order to feel he understands the world around him, she seeks—and represents—novelty, as a result of the very curiosity that made her the woman he initially admired.
His constant anxiety related to living in what feels like an alien culture is soothed by predictability. This would be facilitated by the presence of a partner who complies with his view of reality. This is not because he sets out to manipulate her. It is because his fundamental concepts are threatened by hers. His anxiety grows with his fear of doing “something wrong” because he is never quite confident about what the “right thing to do” might be.
From her perspective, his thoughtful attention may have disappeared the very day of the wedding. He quickly became self-involved and aloof. The stability she admired slowly shows itself to be profound inflexibility. The reticence does not point to the underlying wisdom she assumed was present; she now sees that it comes from his not knowing what to do or say. And his inability to focus on her has come to mean she exists outside his field of interest, where he is apparently content to relegate her."
