I agree about the middle of the night, *@MitziK but if he's refusing to even discuss with OP how to get through this without being dismissive, then she has an uphill and lonely battle ahead. Communication is a two way thing and, as zoesmum* said, he is an adult and should be able to discuss his feelings.
Yes, he is - but, speaking from my experience of having ASD and desperately needing times of no noise, it's very difficult to do that if your internal dialogue is along the lines of;
'Please, please, just stop talking at me. I've been in this house almost 24 hours a day for the last six months and you haven't stopped talking at me once in that time.
We can't go out and get some fresh air and a change of scenery anymore because you're not able to do that.
I can't hear myself think for five minutes or get work done that pays for a roof over our heads because you'll get the vacuum cleaner out to fill the silence.
And then when that stops and I think I can start that really complicated bit of work, you come in and start talking at me about how I must really hate you because I didn't pay you more attention this morning when I needed a coffee and five minutes peace.
I can't sit down and watch a film without you talking through and over it, asking me questions that you might know the answer to if you'd actually stopped talking and watched the film a bit. I can't even answer them because I couldn't hear the bit that explained it because you were asking me what had happened in the scene two minutes ago that we missed because you were talking.
I know it's hard and you're struggling without visits for counselling, but seriously, I'm not even safe to sleep anymore because you're shaking me awake at 3am to talk at me some more.
I love you but you are doing my fucking head in.'
- because you know that actually saying precisely what you feel could result in somebody's else's being hurt and their reaction could be to do all the things above a thousand times more, with added shrieking, wailing and sobbing that 'YOU DON'T LOVE MEEE ANYMORE' to deal with on top.
Far better, I think, for the feelings to be kept private at times rather than adding more fuel to the OP's fire.
