Same situation with us. My partner and I have a joint account that we each pay into proportional to our income (which amounts to ~50% of our income each) to cover rent, bills, pet expenses, fun stuff we do together, stuff for the house... The rest of our money stays in our own separate accounts for us to use on stuff we do without the other person (hobbies, hangouts with friends, clothing, personal purchases). It's worked super well so far!
