OMG!! My first thought was "make a sign!!

So happy to finally realise I'm not alone in my oddness. My AS friend has helped me out a lot, as he's made me realise that it's all part of me & it has its benefits, like being able to see flaws in seemingly-logical arguments (though I am still trying to learn when is ok to point them out & when it isn't). But can't always see the blindingly obvious!
Have you tried hiding your drink/moving it somewhere he can't see it from where he is? Generally, when I'm focused on things it's only things that I can see without moving my head that have my attention. Like I won't think of making a cup of tea when I'm busy unless the cup is in my eyeline when I feel thirsty and something distracts my attention from what I'm doing.
But I really can't see it as lack of respect. I can see what he means by feeling it's belittling if you mean that you'd be drinking wine from a mug, just so he wouldn't touch it!

But just because he isn't focusing doesn't mean that he has an excuse not to take your feelings into account. Yes, for him it's easier to not change his behaviour but that doesn't mean he can't make an effort. If it's really important then you need to make him realise that it's a problem & maybe he could suggest an answer. And if it's not a problem, then try to find a way round it.
