When a grown man believes tidying is woman"s work then he won't change, and there will have been signs of sexist, lazy entitlement before the nuptials
I note you're on mat leave so you work too. He's not the great I Am Sole Earner that some appear to think means his status is higher as he works outside the home.
The numerous threads on here bear out that love goggles convince women they will somehow magically change him after marriage and kids and/or he will come to some great revelation on the housework issue himself.
I'm not talking about men who are a bit slobbish, but open to change. Or those that may not do the round the house jobs you think they should do, but they will do some things and whatever the case, won't see you struggle nor see your function as being a housemaid.
I absolutely believe women should not marry a man if you've never seen him cook a full meal. If you've never seen him stick a load in machine AND put it away. If his place is a mess. & if he lives with his mum and doesn't have to lift a finger, allows mummy to do everything, then be wary about that too. Especially if he has exacting standards but it's mummy keeping things to his standard
Or even where his place is scrupulously tidy, he is very fussy yet you feel he will expect you to be the one maintaining the cleanliness standards he prefers - with no input from him.
Don't rush to show your best self by cooking cleaning tidying around his place regularly - looking through those love goggles again - presenting that you are now in his life as chief cook cleaner washer, to take care of all of that for him.
Then again I guess some men lie, show their "best self" to reel you in. I still feel there are always signs regarding attitude to women and housework though.
Typical passive aggressiveness OP. Making the meal but leaving a shitload of washing up for you to do, so you don't "get away" with doing "nothing".
Call his bluff next time he mentions divorce.
If he pissed off at least it would less mess less stress, for you.
