I've not got time to read all of this thread at the moment, but just to reply to your first post...
He did say that if either me or our son was officially diagnosed, then he'd actually read about Asperger's and see if there's anything that can "be done about it".
That's missing the point. He needs to read up about it and see what he can be doing to help and to understand you better, not sulk that you're not and can't be (and imo shouldn't be) what he expects from an 'ideal wife'.
he'll end up standing there saying the meanest things he can think of to me while I sit on the floor, cry and hit myself.
And that's just abusive. A large percentage of love, or even normal human decency, is to not want someone else to get hurt. If you're that distressed and he's just standing there distressing you further, *sentence ended to avoid expletive descriptions*
Seriously though, he doesn't sound like he deserves to be married. Maybe see if you can try couples counselling or something.
