If his words are being expressed to you and with some vehemence (I am guessing this is the case from the choice of words) then he is being U, if he is the one who is basically doing most of the cleaning.
He is certainly being U to say all of this in anger in front of your DD. This is a matter he should sit down with you over, and you can each listen to each other respectfully.
That being said:
If you are cooking or just plain living (having a cuppa, reading the paper, paying bills, etc) and leaving a mess behind then it wouldn't be unreasonable of him to expect a bit of care that you don't make work for him, swanning off and leaving a mess behind you.
Wrt loos -- I agree with PP that if there is a smell then it most likely arises from him missing the loo and floors being affected.
(Cleaning the loo itself takes less than a minute, a loo brush and about a capful of bleach. Swabbing down the outside of the loo is easy to do with a sponge and a bit of bathroom cleaner. If pee has got into the floor then that is a bigger job entirely. If you have a carpeted bathroom or a loo rug I recommend you get rid.)
I have an inkling though that you not smelling dirt in your house could be something to do with allergies, and it is also possible you have just got used to it. If your home was dust free and clean, then you might notice smells more when they happen. Dusting isn't necessarily time consuming -- damp cloth, swipe over everything. It takes time if there is clutter everywhere though.
How does it happen that there is a pool of mouldy somethingorother in the fridge, or is this hyperbole?
It seems to me that you are being a bit blithe about it all and that your home is cluttered and dusty and maybe not the happiest of places for your H. How much used he drink and was there any particular reason to stop ten days ago?
I would take a long, hard look at the clutter. It is stressful for some people to live in it. If I were you I would meet him at least half way on this.
