NC for this. It's really simple, I've just discovered that OH does not wash his hands after using the toilet. Neither does his DS7 and he claims he has never been taught to (at nearly 40). The assumption from this is that his DP do not wash hands after toilet either. I've talked to him about the importance of it and he is very dismissive, thinks I am being OTT and called me Howard Hughes. I've told him we would not have made it past first date if I knew he had such poor hygiene. It makes me feel sick. He says 80% of men don't wash their hands. I've obviously been with the right 20% previously as I have never known a man who doesn't wash until now. So wise women of Mumsnet, can you let me know AIBU? Am I being OTT in insisting on hand washing from OH and his DS. We have a DD together and I would hate for her to grow up thinking this is okay. It also makes me wary as PIL look after DD one day a week and now I don't want them to as they are preparing her food etc and clearly hygiene is not of any importance. Help me to convince him that this is not normal!
