<prompt> Human: Throwaway account for obvious reasons, but my bf and I cant come to terms with the moving in and finance situation... so I thought Id ask if I was being crazy.Weve been together over 3 years and he currently owns his 2 Br apartment uptown. Mortgage maintenance approx 2800 a month. I currently live in midtown with 2 roommates and pay only 1050 for my room Ive lived with my roommatesapartment for over 5 years. I travel for work frequently and am only in my apartment probably 2 weeks a monthI find it oddwrong to contribute and help him pay down his mortgage, while I know if we do end up getting married, well be signing an iron clad prenup, where Ill have no financial claim to the apartment. I think its very important for ALL couples marriages to have a prenup. Not just the wealthy.Because of this, Ive asked for a super discounted monthly payment of 950 a month. He says Im being ridiculous and said the lowest he could go is 1150 a month. This way hed still be paying more than hes paying now He has a roommate now. I dont want to pay more to live farther uptown, where Ill add 2530 minutes to my commute everyday. I then asked if my rent each month could contribute towards buying shares or a small percentage of his apartment So its a mini investment for me on some level I get a VERY solid no there as well. Are my requests outrageous? How do couples move-in together, when theyre paying down one persons mortgage... when the other person has no financial right to the asset? Id appreciate any advice or insight on how to navigate this.  <response>: My gf owns her home. I pay more than 12 the monthly expenses, but i am still paying much less than what my apartment cost me. I do not care that i am paying down her mortgage. I was doing that for my landlord.
