Welcome, BTW.
So, there's a lot to unpack here, but I am in my mid-50's and I understand much of what
@Gerontius and
@Gerald Wilgus said.
I have been married for 35+ years and wasn't diagnosed until I was 52,...ASD-1,...and although it is not "language" we use in the US,...my psychologist sort of rolls her eyes and acknowledges it as "Asperger's condition". I am not one to get hung up on the label. I am well aware of what I have. That said, unlike your husband, I was actually happy to finally,...finally,...have a diagnosis. It gave me some answers to questions that had lingered in the back of my mind for decades. Then came the steep learning curve to understand myself within this context. So many things in my life became so much clearer,...my strengths,...my weaknesses,...how better to interact with people around me. Furthermore, my wife sort of left it all up to me to sort these things out. Frankly, it took almost a year or so for her to settle into the idea that she was married to an autistic,...because, in part,...I think she had developed a "moral diagnosis" of me over some 30+ years of marriage,...and now she had to reassess her view of me, which, I am sure, was not easy.
Obviously, your approach to the diagnosis is quite a bit different than my wife's. Now, I am trying hard here to understand the perspective of your husband's,...and I may be way off here,...but if I was perceiving my wife as "pushing me" to talk about things I haven't quite wrapped my mind around yet,...I would push back, no doubt. Furthermore,...and I don't know if this applies to your husband,...but like a large percentage of autistics,...I have alexithymia,...which means I don't actually know how I feel at any given moment. It may take me minutes, hours, even days to process a social interaction,...so, no matter what,...I will respond in an "inappropriate" manner given the emotional content of a social interaction. Later,...if the person means something to me,...I will walk up and apologize. Furthermore,...I grew up in a generation where males were absolutely expected to suppress their emotions,...so it could be that your husband is also very good at emotional control,...until he can't. I like to say I have "a very long fuse",...and at the end of that fuse,...a very large bomb.
Fear of saying the wrong thing,...I have this, as well. Better to stay silent than risk saying something inappropriate,...because, frankly,...part of the autistic condition is not processing all the subtle nuances of communication (voice inflection, facial micro expressions, body language, cultural and emotional content, etc.). He may have found that he is often misunderstood,...a very common thing with autistics,...and it is quite emotionally upsetting to be put on your back heels by someone who misinterpreted what was said and/or how it was said. I use direct language,...most other people use indirect language. Indirect language, in many circles is most common and even is perceived as "non confrontational" and even "polite",...but an autistic may perceive it as "deceptive" and immediately puts our brains on "alert",...so we might not respond in the way one might normally expect. I don't want to be put into a position where I have to try to "read between the lines" and interpret what was said,...because my ability to process all that communication information and put into context and perspective,...that's a tall order for me,...I'd have to "chew on it" for a while before answering appropriately. The thing is,...most communication occurs quickly,...back and forth,...and many autistics are not good at that. I do OK one-on-one, but add another person into the group,...I shut down and become mute pretty quickly.
At any rate, I hope this gives you some insight. HE needs to sort these things out on his own,...and only if HE wants to. If you push, he will likely push back. He may not have any sense of how he is feeling,...he may be just reacting,...so you may be asking questions he literally is incapable of answering.
Take care
