<prompt> Human: Ill make this short and sweet:SO earns a lot more than me, about 30K more. We dont have kids, do have a house. He wants to spend up to 60 of his own income on a car, I think its too much, even though we could technically afford it - I just think its a waste. Ive know hes a car guy so Ive agreed 50 a top budget to be sensible but still gets a good portion of what he wants.Weve not yet pooled finances not engagedmarried yet but plan to be. Hes using this discussion to question the benefits at all of joining finances because he cant buy what he wants as Id have a say in the matter, despite earning less.Any help?  <response>: As a one off cost? Or 60 ongoing like a rental?Either way I think its important to try and work out the full cost, then ask is there a better way of spending the money to achieve our goals?. For that youll need to actually work out what your long term goals are, and how you want to fund them. How much does this delay buying a house? Kids? Retirement?Unless youve got a current item in your budget saying fancy car then the money is coming from one of your other goals. Hes using this discussion to question the benefits at all of joining finances because he cant buy what he wants as Id have a say in the matter, despite earning less.Well, its something definitely worth talking about, different couples pool things in different ways and youll need to come up with a way of working together on this. Ive know hes a car guy so Ive agreed 50 a top budget to be sensible but still gets a good portion of what he wants.Is 50 of his income a sensible amount to spend? Or will that just lead to his annoyance he couldnt get the one he wanted and your annoyance that hes spent so much?
