@Autumnmornigs OP, I wonder if reframing what this is would help to start. This isn’t a partnership, but maybe a ‘traditional’ marriage. Is this what his parents did? However, as this doesn’t seem to be the family agreement that you had when entering into it, this feels somewhat unfair.
As others have said, it feels like you’re his housekeeper, his secretary, his nanny. He is financially supporting the roof over the head of you and your children, so that has some value, however adjusting expectations from him contributing to you and the children I think might be helpful.
Please, please, please give yourself permission to have a life outside of mum, to lean on support. There’s a saying, that it takes a village to bring up a child, so there is absolutely no shame, or failure, by needing to have some time to yourself, while the children are in the safe care of somebody else. You would be a better mum for having that break, that contrast.
Would you be able to organise time away for yourself during the weekends when he is around being the fun dad? Even if you just go off to the library or to Costa and read a book for a bit or watch a film, anything that would help you just have a break from being on duty, even if just for a few hours, this might help you start building the confidence in granting yourself permission. Only you can assert this for yourself. He may not like it, and he has clearly shown he doesn’t understand it, or agree with it. He doesn’t have to. He is the boss of himself, he is not the boss of you.
As for the suggestions about leaving him, well, you probably wouldn’t notice too much difference in how your life is at the moment, however you would get to choose what work you do when you organise to see friends and family, but you would still need to lean on maybe hide help, if a natural situation might be tighter. However, sometimes it can be worse being in a lonely relationship than not in a relationship, I would seriously be weighing up the pros and cons of staying and leaving.
He isn’t going to change. The way your mother sounds, probably set you up for the husband that you have.
Either way, it’s about what you do now moving forward that matters. Certainly reading into coercive control, emotionally abusive behaviour, would probably be helpful, just to make sense of what you’re experiencing perhaps.
All the best for this, OP, there is some tough stuff ahead. But it’ll be worth it!!
