<prompt> Human: Hi PF,Hopefully this is the right place for this type of question. Also, please ignore my username... My long-term girlfriend over 5 years and I have been having arguments about sharing finances lately. Ill try to keep the details concise and objective. - We currently live together in a rented apartment, and are looking to buy a house - I make 15k more than her, but we both make pretty good money - I am on the higher end of the salary spectrum within my field - She is very close to the low end of the salary spectrum within her field, and could easily make more than me, but she likes the perks of her job working from home often, low-stress, great hours and therefore doesnt want to seek a higher-paying job that may have not have those perks. - I work longer hours and have a higher-stress job, so she ends up doing far more of the laundry and cleaning - This is debatably relevant, but she has a quite a lot of money in savings over 200k, which is significantly higher than what I have at this point. This is due to a combination of factors - primarily because she lived at home while I rented and her parents paid for her college while I had loans, but also because she is much more stingy on things like eating out, recreation, etc. - The location of our workplaces in different states, and the fact that she doesnt have to commute for a portion of the week, dictates that we will need to buy a house in the state where I work. This will cause her to pay additional taxes than she would if the house were in the state of her employerEssentially, she thinks that in order to feel more invested in each others careers, we should direct a percentage of our salaries undecided number, but below 20 to a joint account that would be used to pay for all the purchases that we split - bills, vacations, eating out, etc.. So I would end up paying for more of our joint purchases, but we would still maintain our separate accounts.For a lot of situations, I think this would be reasonable. But my big hang up is that she could easily be making more than me in her field, and chooses not to because she works great hours, is never stressed, and works from home often. Meanwhile, I am in a stressful career making what I make because I dont want to be undervalued in my field, even though I could take a lower-paying, lower stress job. I dont feel that I should have to pay a greater percentage for everything we purchase so she can keep her terrific work life while I am working bad hours and stressed. It only makes it worse that she is so far ahead of me in terms of savings, and if I pay a higher percentage for everything, I obviously will catch up slower.Additionally, she thinks that I should pay some additional amount to make up for the fact that her take-home income will take a hit due to the higher taxes from living in the state of my workplace. I see where she is coming from, but at the same time, she works in a state where my field doesnt really have any career opportunities. I dont think I should be penalized financially because she works in a fairly remote location that I couldnt possibly get a job close to.Basically, I initially felt strongly that I am in the right on this, but after arguing for so long about it, sometimes you start to question things. So, PF, do you think that I am justified in not thinking I should pay a higher for our shared purchases? Or am I being unreasonable and selfish?Sorry for the long post. Any feedback would greatly be appreciated.  <response>: This is easy. You arent married, dont combine your finances.
