If men are better cooks, then why are women expected to cook?

I’ve heard this a lot and if it’s true then why do women need to cook? If that’s the case, I want my future partner to cook every single day where I don’t have to. I can’t believe I wasted my whole life learning to cook if I’m bad at it and men were the ones who are better.
