<prompt> Human: My SO and I have been together for 7 years and are both 23.HIM: working for 2ish years, makes around 65kyear plus bonus, projected 10-15 raise next year, almost paid off loans, car payment , car insurance, cell phone payment, other misc fun expenses, lives at home since college to save money ME: graduateprofessional student, 65k trainingfellowship job with projected salary 80-90k after a year, only pays for cell phone bill, Netflix, tuitionrent paid for by school, no loansnbsp;SO and I were originally long distance, I now live about an hour away wo traffic. Weekend visits since undergrad of every 2 weeks eventually changed into every weekend to now where he basically stays with me when he is not too tired to drive. SO works in client services, so his schedule is erratic. Hes here few weeks he has off between clients, to 5 nights a week, to just weekends during really busy seasons.I live in a tiny student studio apartment, making this difficult. My new job will be in another expensive area California, where a one-bedroom apartment is at minimum 1200. An apartment that can fit both of us comfortably for extended periods would be around 1500-1600 minimum. SO brought up the idea that it is basically unfair for him to not pay rent, especially now that I will be using my income to pay for living expenses. I will still be about an hour away from his house, maybe 45 minutes-1.5 hours from his clients. nbsp;Im struggling to figure out what is a fair split when it comes to rent between the two of us. I tend to feel bad about asking for money, partly because he tends to overestimate and feels like he should pay more as a provider.Would it be fair to say that if we find a place for 1600, his portion would be around 636 53day 12 for an average of 3 days a week? That seems too much to me, even though 3 days a week is kind of a conservative estimate. I dont want to feel like Im nickle-and-diming him, but I want to have concrete reasoning for both of us to the amount we are paying so our mutual guilt doesnt cause any issues. Help?nbsp;TL;DR: Im moving, boyfriend kind of lives unofficially with me part-time, we want to make it official but still part-time. How should we split our rent?  <response>: With the projected rent numbers youve given, Id say he should pay the difference between the kind of apartment youd get if it was just you and the apartment youre getting because of him. So in this case, about 3-400month
