As a dual income married couple, we managed our money independently for five years before transitioning to a shared household approach. There were benefits to both, but treating our household dollars the same way business partners do leveled-up our earning power. Some are better at earning, some are better at managing, some are good (or terrible) at both. Assigning responsibilities doesn't have to an old school practice in gender-normative behaviors, but in all cases treating "this money as my money" won't do you any favors when it comes to wealth generation.
