how does a millionaire couple distribute expenses ?

they distribute their common expenses – like rent / loan payments , utilities , eating out evenly – meaning they divide it into two

rest of the money is for individual expenses – like eating out , going to games – no questions asked on how they each spend it

some money also flows towards savings , retirement , investments

they also schedule some time for budgeting and money talk once in 15 days and then see a movie at home after that – so that this can be a fun exercise.
