<prompt> Human: We 23 have been together for 7 years and will be moving into a new apartment. We have decided that we will pay for joint expenses Rent, groceries, entertainment as a percentage of our income If I make 50 and she makes 25 Id pay for 23s of these expenses. What would be the best way to facilitate this arrangement? are there joint creditdebit cards we can use? Other suggestions and advice are appreciated.  <response>: Been married for 8 years, never had financial issues with my wife. For what its worth, heres what we do:- We dump all living money into one account--money we need to live.- Anything thats left at the end of the money, we first take and put into savings investments the amount weve decided we should in order to meet long-term goals- Anything thats left after this goes toward debt.- We dont even think about dividing out expenses. My money is hers, and her money is mine, therefore, whatever we spend, it comes out of our account. - We decide together anything over 20 thats outside of regular expenses such as utilities, food, housing, etc. Were generous with one another. We are both reasonable, so we wouldnt even think about blowing a few hundred bucks on something without consulting the other person- We have always paid off each others debts and obligations with no resentment whatsoever. When we got married, everything that was mine or hers became ours, for better or worse- We track everything in a simple month-to-month spreadsheet. Everything is 100 transparent, even to the point of laying out to the penny how much each of our paychecks are, where they are being deposited, etc
