IA probably BU but would value opinions as I feel really cross.
Back ground - DH has always been a nail biter. Stopped for a few years (when he smoked) but restarted (when he quit smoking). It's a comfort thing, he usually does it in the evening when he's watching TV. Sometimes I find it annoying as its not a little nibble but whole hand in the mouth, gurning and chewing for hours. It's weird. But everyone does weird things and I would rather that than smoking or drinking (his DP and B all have serious alcohol problems) and I just ignore it.
We holidayed in a developing country for 2 weeks, got home Sunday. I repeatedly reminded him again and again about the danger of putting your hand in your mouth without washing them. I have lived in the country and it is very very important to maintain good hygiene. On the plane on the way home he was sat a few rows away from me and DC and spent the whole flight chewing his hands, got off the plane collecting the bags he was doing it again and I reminded him that someone had been sick on the plane and we needed to minimise risk of illness. He stopped for 2 minutes then started again - probably because he was really tired.
Now we are all ill, he was unwell on Monday - D&V the rest of us started today. I am really cross with him even thou I realise that we may well have caught a bug anyway.
AIBU to be annoyed with DH for constant nail biting and expect him to stop or at least try and not do it in places packed with germs like planes/bathrooms etc?
