<prompt> Human: I know everyone says you should spend what you feel comfortable spending but I tend to overspend new F-150... So, I would like some outside opinions on where I should be comfortable. Im a 25 YO male, engineer and my gross income is 75K. I have 16K in my 401K, 12K in ROTH IRA, 2K in my robinhood, 5K in savings and 2K in checking. My fixed expenses car, rent, insurance, food, ect.. total 2,025.00 a month. I was an idiot and bought a new car after graduation and owe 21K 500 per month. Kelly bluebook values it at 22K trade-in so I could sell it need be. x200B;She is in her second year of medical school and just took out her first loan and will have approximately 75K in debt at graduation. This and my car will be our only debt to balance.x200B;During our initial conversation she hinted that her friends ring was 15K and her husband is an engineer as well. That seemed a tad high but I have no idea what things like this should cost. She isnt pretentious in any way but she does come from a very well off family. I want to get her a ring that she is proud to wear not only around her family but also around her school friends very pretentious without putting us in a terrible situation. x200B;We are still approximately 5 months from getting engages so I still have some time to save.x200B;Any opinions are greatly appreciated! Also, should I trade down my car for some extra cash?  <response>: Trading in your car is crazy, this isnt gift of the magi.Id recommend surprising her and taking her to a ring store to see what she picks out and go from there. You dont need a 20k ring, especially if you plan on buying a house anytime soon.
