So maybe he acts like a child so I have to impose rules like a child
No, that's not how it works. You talk to each other like adults and treat each other like adults. You are his wife, not his mother!
What is auditing your wardrobe? because I don't think I've ever done that before!
Just didn't think it was my job to also smell the stuff in the warp be and establish what needs to be washed!
Well then don't! If there really is a smell coming from the room, talk to him about it. Ask him if her can identify the source.
You constantly pick up and tidy up after him, of course he won't do it for himself - he doesn't stand a chance of meeting your standards.
House rules are negotiated and agreed as a household. They are not dictated and imposed by one person. You are not in charge of everything that goes on in your home! It is his home, not your workplace, you need to be far less controlling because home is supposed to be a happy place.
He always gets the hoover out to apologise for calling me Horrible and obnoxious and making me smell his nasty clothes.
He didn't MAKE you smell his clothes, you chose to because his standards aren't good enough for you. However, he shouldn't call you names.
You are grown ups. When he has finished hoovering, sit down, pour a glass of wine and talk to each other like adults. If you are reasonable, I'm sure he will be too, but you need to back off a bit and listen to him.
