<prompt> Human: I am having a disagreement with my boyfriend at the moment, you can check my post history if you would like to read more about it. We have been living together for three years so far. I make 35k and he makes 75k per year. We each pay for our own health insurance and cars. He has a son and pays for everything regarding him split with his ex, but I do provide some childcare and help with homework, which I am happy to do. Any home renovations we each pay 5050 on. Right now my expenses are as follows per month:Rent - 600Both our phones - 147Pet supplies - 100Groceries - 200Car - 400Health insurance: 75His are:Mortgage: 450Car: 400Groceries: 200Utilities: 300Health insurance: 265What do you think is a fair amount for me to pay for rent? Should I really be paying half if I am only one person, yet he is paying for himself and his son? Any insight would be very helpful. Thanks!  <response>: This is a relationship question. There is no one right answer.I am confused here. You pay rent and he pays mortgage? So its more like hes the landlord and youre a tenant, right? Or in other words, your rent is helping him build equity in his house. If thats the case, its not a split. What he pays on a loan in his name is not relevent to fair market price of a person boarding in a shared house.Why are you expected to pay 50 when HIS house gets a renovation? Its not your house. If youre a tenant renting, you should pay zero when your landlord decides to improve his own property.If youre paying rent, some consideration should be made for the work you do a tenant normally wouldnt. For example youre the built in babysitter and tutor. How much would these services cost? From a financial standpoint this does not seem equitable. He gets his house improved 50 paid by you. He doesnt pay you to watch or teach his son. He wants you in the role of wife, while financially hes the landlord who wants 50 of his home expenses paid AND get some free childcare. Youre not married. Relationship can end at any time. All that money sweat equity you put in his home is now all his. What do you get? Nothing.
