There's another thing that strikes me really strongly.
The Relationships thread on MN (all the regulars have gone away and stopped reading this now, yeah?) has a very very strong culture of judging the person.
"My OH said x,y,z; behaves like l,m,n"
... 15 posters leap in
"He is abusive" "leave the bastard" "what a prick" "what a tw*t"
It's very black and white. Ending the relationship is almost always the advice, vociferously given.
Me, I'd rather label the behaviour, just as we would with a child.
Behaviours x,y,z. We have lots of freedom about how we interpret those behaviours. They might be abusive; they might be a symptom of an illness; they might be a symptom of a disability.
And if a rational explanation of those "abusive" behaviours is as a symptom of a disability or illness, then we can get out of the whole persecutor/victim mindset and find whole 'nother ways to navigate (and escape what feels like abuse).
Someone leaving a room in the middle of a conversation is only abusive if we decide to interpret it that way. Once we stop interpreting idiosyncrasies and different ways of behaving through an NT cultural norm, that frees us up to be much more loving, much more open, much more accepting. It used to drive me crazy when I was left alone mid-sentence, or a conversation was closed down. Now I am much better at thinking "ah. Poor timing, too in-your-face; I'll send an email instead, or I'll phone in my tea break when we are both relaxed"
Like I said upthread, our journey to a happy family life began a good while ago. I am so so so glad we stuck with it. There are some really really great things about being in an AS/NT relationship, like having the freedom to have your own social life; and having a wonderfully predictable structure to daily life; and being able to make star shapes in bed as long as there aren't any children in it; and being able to eat whatever you like because the other person might well prefer to prepare their own food and eat alone; and whatever the things I enjoy about it won't be exactly the things that you'd enjoy.
[and for the crunch moments, well, the Samaritans phone line is there for a good reason... and they don't put interpretations or judgments on what you say, they just listen]
And another random aside: I've long thought it is really valuable to have different people in one's life who fulfill different roles: someone to be a non-judging confidante; someone to (I don't know) play board games with; someone to share a home with; someone to provide physical closeness at just the right level; someone to have a laugh with; someone to work out work-related problems with; someone to hang out with the children with... and the mistake our NT mainstream culture makes is to assume that one person and only one person is the person to fulfill all those roles with. Most of my Mum friends have workaholic and/or AS partners (or are single). So we hang out together with the children at weekends. No need to resent the AS/workaholic partner for being absent - other people are fulfilling that need for hang-out company.
