<prompt> Human: My GF and I decided to open a joint bank account while keeping our own separate bank accounts. But I am confused how we should track our spendings.I thought of us both putting in money into the account on a bimonthly period and using that money for mostly bills but also for things we both needuse in the house food, paper towels, etc.The part I am confused about is that our responsibilities for the bills arent equal. For instance, I am responsible for 65 of the electric bill because I have more intensive usage and an always on computer. I dont know how to track that effectively.If we both put in 250 each paycheck, or 1000 combined for the month, how do I track the different proportions of spending for bills?It almost seems like I should open instead of one, but two different accounts checking and saving; one for bills only and one for a pool of extra money. Can anyone give me advice?  <response>: Close the joint account. When you need to share expenses, just have one person pay the other. My girlfriend and I would use a spreadsheet with all shared expenses entered in with one overall payment from one person to the other once a month.For example, whatever the electric bill is, she pays you 35 of that and you pay the bill.
