"Why is it that my husband [with ASD] never considers my point of view? He's always right - and I'm always irrational and overly-emotional [according to him]."
A person on the autism spectrum has difficulty understanding social cues, implied directions, and how to "read between the lines.” Instead, he learns facts. He does not "take in" all of what is happening around him that involves the rest of the world, only what directly impacts him.
Your ASD husband has probably had many conversations that have generally been about knowledge and facts, BUT NOT about feelings and interactions. As a result, he does not really know how the social-world works and what one is supposed to do in various “socially tricky” situations.
This can apply to even the smallest situations that you, his NT wife, may take for granted. Not knowing the unspoken rules of situations causes anxiety, which leads to many of the behavioral problems you witness as your husband tries to impose his own sense of order on a world he doesn't fully understand.
The ASD individual creates his own set of rules for everyday functioning to keep things from changing - and thereby minimize his anxiety. Sometimes, he just makes up the rules when it is convenient. Other times, he attempts to make them up by looking for patterns, rules, or the logic of a situation to make it less chaotic for him and more predictable and understandable.
If there are no rules for an event or situation, the ASD individual will create them from his own experiences based on what he has read, seen, or heard. He will often have a great deal of information to use in reaching his conclusions and forming his opinions. As a result, some of his conclusions are correct - and some are wrong.
Your husband will rarely consider your point of view if he does not consider you to be knowledgeable of the topic in question. If you can’t [or don’t] provide “facts” and evidence that back-up your opinion, your opinion will mean nothing to him. Therefore, he will argue with you about your opinions if different from his own. He thinks that his opinion is more logical, so he chooses his (this represents rigid thinking).
The person on the spectrum finds it difficult to be flexible and consider alternate views, especially if he has already reached a conclusion. New ideas can be difficult to accept ("I'd rather do it the way I've always done it"). Being forced to think differently can cause a lot of anxiety.
So, you must never over-estimate your husband’s understanding of a situation because of his high intellectual ability or his other strengths. He’s someone who has not fully figured out how the social-world works – and he could use a road map and the set of instructions (one example at a time) from YOU, his compassionate coach and wife.
