DP and I are planning on moving in together in the near future (when it’s possible with the current situation...). We’re in our twenties, no children. I earn slightly more than him, about 4K more per year. This is the first time either of us has lived with a partner, just the 2 of us as a couple and no other housemates etc.
He thinks rent, bills etc should be split proportionately according to income, so I would pay slightly more. I think we should split everything 50/50, as I have done in the past and as is normal for housemates/friends living together. I KNOW living with someone you’re in a relationship with is different to living with a friend/housemate, but I can’t understand why I should be effectively subsidising his living costs when we’re not married and don’t have joint finances? His reasoning is that it wouldn’t be ‘fair’ as he would then have less spending money/for savings than I would. I said that this is true now, when we don’t live together, so what’s the difference? He thinks that when you live together you effectively become a ‘unit’ and so it should be more equal.
In reality, because I don’t earn that much more than him, I know the difference would be minimal if we did split it proportionately. However I think it’s the principle that bothers me. I think it should be 50/50 but you should both live within the lower-earner’s means - ie. if he says he can only afford 600pm for rent, then I can’t expect him to pay more than that, and if I want a more expensive house then he has every right to ask me to subsidise him. But if we both live in a place that he can afford, why do I need to pay more for that? AIBU?
