<prompt> Human: Hi Reddit:My girlfriend recently purchased a car, which she paid in full. We both want to figure out a fair and equitable financial approach to sharing the car.Logistically, we live separately in two different cities about 30 minutes away with no traffic. We currently see each other on the weekends where we run errands, drive to places where we can hike or mountain bike. We also like to go backpacking or camping at least once a month and sometimes more when timeweather permits. The car will stay with her where she lives.In the past, she had an old car that she had for years before we met. Once we were more serious, I paid for half of the insurance, half of all gas, and half for any partsservices. We broke up for a few years, got back together, and became serious again.Here are some other things for a bit more context.- I make almost twice as much as she does- My rent is twice as much as hers- I pay 200mo. extra for a garage in my apartment I live in a very dense city and its impossible to find street parking- She doesnt havepay for a parking space at her place- The car is new and was a substantial amount money- Not that it matters, but we are both womenWhat is fair?- pay a certain amount per mile?- pay a certain amount of money each year - like a rentallease?- pay for a portion of the insurance?- how much gas should I pay for?Thanks so much for taking the time to read this.__________________________________________________________________updated: 928x200B;Thanks for the responses. They have been extremely helpful.x200B;I wanted to also point out that when we got back together, she eventually sold the old car when it was unusable and we were carless for two years. During that time, we took public transportation or ride hailing apps e.g., uberlyft to see each other or get around locally. We also rented cars to take our road trips which we split in half. I say this because since we rented cars and shared that cost, it does feel unfair if she bare the burden of buying a car and I get the benefit of not having to split car rentals.x200B;Thoughts?  <response>: I dont think you need to pay for any of it. She wanted a new car, she got one. You dont live together or share expenses. If you borrow the car, put petrol in it. If you go out together, pay parking and petrol.
