What if my boyfriend has to cook by himself after work? I said that a man only needs to do a good job in his career, which is a woman's job, even though his family is rich.

Boyfriend has to cook by himself after work, which means that he has been cooking at home and is used to it. I think it is also a good thing. Don't clearly prove that he cares about you because the boy who often cooks by himself tastes better. Maybe your cooking doesn't suit his taste. As long as both sides like each other, don't care who does the housework.
