Maybe I'm bloody minded but I think this behaviour is deliberate.
I think it's his way of trying to put you in your place.
To disrespect you.
To make it very clear that you are subservient to him.
Its extremely PA I believe.
It actually takes effort and energy to disregard this type of request from the person you live with.
The utter simplicity of what you are asking, yet his huge difficulty in working with you.
The effort for him to NOT comply, that is what you should be reflecting on.
As others have suggested, no longer wash his clothes or put tge plates in the dishwasher.
I wouldn't discuss it further. I just wouldn't do it.
People can reveal themselves in very small ways.
I believe he is here.
Watch how this plays out.
It will reveal a lot about him OP.
You will be vulnerable when you have your baby, I hope you have lots of support around.
