My husband is constantly untruthful about whether he has washed/cleaned teeth/ changed underwear. I ask him if he has done any of these things and he nearly always says he has. Checking toothbrush/wash basin tells me he hasn't. He does not want me to help and he gets cross if I try to persuade him to be a little cleaner, especially with his teeth. Life is challenging enough without having arguments about cleanliness, but how do I ensure that basic, personal hygiene is carried out. He recently has a really bad bladder infection, which resulted in a frightening increase in his confusion and irrational behaviour. I wonder if this infection was a result of his poor hygiene. My husband is 6ft and a big man, whilst I am 5ft 2ins, so dealing with a difficult chappie isn't easy! I'd be grateful for any advice.
