<prompt> Human: Hi rpersonalfinance! Love this thread, there is so much great content to sift through. I really appreciate those who are willing to post their own experiences and Ive tried to help where I can too. Now, I have my first financial problem in my life. My partner. Hope couples in similar situations may be able to help. Ive been fortunate enough to be raised by working class parents that taught me a good deal about money and saving. Im in my twenties, own a property, have savings, no debt etc etc. However, my SO comes from a pretty wealthy family and, while he has had to work very hard for the family business, has never really learnt the value of a dollar or how to budgetsavenot blow his last 100 on candy. Hes very much living paycheck to paycheck and even though he earns about 3-4 times more than me, he often has to borrow money to pay rentbills. He always pays back with the next paycheck because he does earn good money, but weve got to the point where he acknowledges that he cant get anywhere being this irresponsible. He has no idea where the money goes. As someone who has had spreadsheets planning for retirement since I was 14, this blows my mind. Some weeks he will get paid over 2000 and it just disappears. Im pretty sure he just lives a life of complete convenience will take toll roads to cut 5 min travel time, buys groceries from the petrol station, takeaway every day etc.. Ive heard of a few situations where one partner takes full responsibility for the household finances and am hoping to gather advice on this. How did you start? Weve discussed this arrangement so that I can manage his finances but Im not sure exactly what to do. Did one person just have complete access to bank accounts and just give the less responsible person spending cash for the week? We dont live together, but we stay over at each others places regularly. Any tips on how to teach not preach him about basic budgeting or financial skills? Please dont suggest podcasts or websites to show him. He is well intentioned and wants to learn, but he works with his hands and is very much a luddite. Are there basic games a little simpler than Monopoly? So for any couples where one person is more fiscally responsible than the other, any tips would be appreciated. Thanks in advance!EDIT: SO much great advice to mull over. Thank you everyone for contributing!  <response>: I can relate to this is some ways. What worked well for me was a YNAB type of budgeting. So I know not to just buy extra fancy things when Im grocery shopping if theres only x left in the grocery account for the week. Also, two more things: budget some kind of free spending for him. Something sensible like 50 to 80 a week that he can do whatever with. Trying to immediately become a frugal spender isnt sustainable. Second, pick something enjoyable to ave toward. My wife and I took a vacation as a way to affirm that saving toward a goal was a worthwhile way to live. Our savings improved over time as a result.
