Is it me? Aspergers and silly rituals

Oh good heavens, he is driving me mad!
My husband has Asperger Syndrome, undiagnosed by a medical  professional, but having worked for many years as a mental health nurse, I am pretty sure he has it, although I have been reading recently that there is a fine line between AS and the extreme male brain. Well whichever it is, it is bloody hard to live with. I am writing this blog as a vent for my frustrations, and also to hopefully share some coping strategies  with others in the same boat.
He has lots of rituals and they are getting worse, many are connected to bodily functions of some sort, eg very loud and frequent nose blowing (for god's  sake, if everyone in the country made as much noise blowing their noses we would all be deaf!). Lots of others too, and they seem to wax and wane in importance to him. At the moment, the ritual of the month is fiddling with his hair, grabbing a bit of hair, twisting it round and tugging it hard. This afternoon we were sat in the conservatory after working hard in the garden, he was continually pulling at his hair, and also told me about 5 times in 10 minutes that he needed to get his hair cut. Eventually, after biting my lip for as long as I could, I said in a neutral, non confrontational tone, "you'll get a bald patch if you keep pulling at your hair".
 Immediate bristling by him, "well I won't touch my own hair then"
Me in jokey tone "ok, don't want your hair falling out eh?"
Him "it's obviously annoying you"
Me "well yes it is, you are constantly fiddling with your hair"
Him "well when I get it cut it will stop being uncomfortable"

Uncomfortable hair? What? I know that people with AS can be over sensitive to sensations, but uncomfortable hair? Give me strength!

My main coping strategy is to keep out of his way when I find him particularly irritating. I am so lucky as we don't have any children living with us now, so I don't have anyone else to consider most of the time, and can go and sit in another room if I am struggling. That has just made me think, is it me who is irritable and intolerant? Who knows, but I will keep writing, it may keep me sane!
