So, now you know. You need to realize that when you elect to become a dependent, that is what you are, a dependent. That is not, by nature, a relationship that was ever intended to be between equally valuable adults. Men typically have zero appreciation for the work of housewives and even less respect for it. He does not see you as equally valuable. He has let you know that he sees you as a child/subordinate he cares for, and the money he earns is his money. That is traditionally how that type of marriage works, this nonsense that a housewife has a say in how money is spent or has any control over money has always been untrue. Many, many women naively believe the fairy tale that men want a housewife because they respect that work and think it's important, but when the rubber hits the road, they communicate what they have always believed, that it is not anything they consider worthy of respect.
If you choose to stay at home and do the difficult and important work of turning little humans into capable adults, you will have to realize that while other women realize your value, he does not and won't. If you're looking for respect and appreciation from him, you won't get it. But please know that he is WRONG, what you do IS valuable. More valuable that his 9-5 job, for sure. And harder.
That said, once those kids are in school, I would advise you to start working. That way, when they're grown, you can support yourself should you need to. Once you start earning, he will respect you more.
