Welcome to Steemit :) I understand your opinion and i like it how you think ;) In my opinion it is also possible, that both genders could change roles anytime, depending if enough money is there and that both genders have enough free time. I like it to cook by myself, so in this time my girlfriend could do something like write a story on steem :P
That's awesome that you cook for your gf, my hubby isn't the best cook ( don't tell him I said that) and don't get me wrong I'm no superwoman and my husband doesn't expect me to do everything but with any relationship it's give and take.
