As soon as I saw your thread title, I thought of my ex who has AS. He was actually diagnosed by Maxine Aston and her books are very good.
The 'look inside' was indeed very enlightening - and long, almost the whole book 
Reading it reinforced my awareness that in order for this relationship to have worked I would have had to continually work, think, be aware, make no assumptions, be ever-vigilant, protect him, translate for him, interpret for him, never relax - it was too exhausting and unrewarding.
Can I ask BBB, do you have personal experience of AS?
