I have suffered from OCD in the past so I'm aware I could be overreacting here and your perspective will be taken on board.
DP does (or fails to do) a number of things which I see as disgusting, but he thinks I'm being a nag and there's no issue. For example, in the past 24 hrs:
I asked him to run a bath for the kids. He knows I always clean it first but thinks that's unnecessary. It hasn't been cleaned for a week because we've all had showers all week, but the shower is over the bath so I think it needs cleaning because there are hairs etc from showering. He then takes the baby's nappy off and puts her straight in the bath even though she's done a poo. The other dc are asking to get out because there's bits of poo floating around, DP shouts at them when they say he should have wiped baby first saying the point of the bath is to clean her.
He uses the same cloth we use for the highchair and worktops to wipe the floor and bin.
He doesn't use a sponge or cloth to wash up, just dunks things and gives it a quick rub with his fingers.
He doesn't wash baby's hands before giving her food.
He doesn't think 3 yo needs to wash her hands after going to the toilet.
Last night we had our dog, cats, rabbits and chickens out in the back garden who obviously all poo. DP put the crawling baby on the lawn this morning to crawl around without doing anything about the poo. I just arrived to find her putting grass with chicken poo in her mouth.
I could go on. Aibu to think he is disgusting?
