As long as you accept this, you will be bullied by them all.
The best thing you can do is start making plans to leave and see how it would look like.
Making plans gives you control in the situation and helps you feel less powerless.
You are not going to want to stay in this situation so start looking at what your options are.
Remember your partner gets defensive and angry to SHUT YOU DOWN.
It is what controlling abusive men do to get their own way and to train you to not object and to do what you are told.
You may not reise this but you are in an abusive controlling relationship and it will not get better on its own.
I'm sorry.
Reach out to family and friends.
Can you pack up and leave with the baby to show him you will NOT tolerate this any longer?
Are your parents supportive?
I am old and in my experience if you do not take firm action you will be looking to exit the relationship within two years.
You do not want to get pregnant with him again, so be VERY careful.
Years ago my friends sister had her MIL at her door at 9am to "help"....she took over every day. It was ruining her mat leave.
Her husband couldn't and wouldn't get it.
He kept saying that she was ungrateful for his mothers kind help.
She couldn't breathe.
She rang her parents and her father collected her and he came home to an empty house.
She simply refused to return and he had to drive to her parents to see the baby for months.
It had all given her a bit of PND.
Supportive help that is welcomed is truly fantastic, conversely the feeling that others feel entitled to your home, life time, and child is suffocating.
Only you can stop this happening by organising yourself so that you are not powerless.
