I’m feeling like this is not quite as clear cut as most people seem to think.
so my understanding is that up until now you have not had children…. And you are both able adults, just with vastly different incomes. That you are living no doubt in his very luxurious house, being taken on nice holidays you couldn’t afford etc, and all you are contributing is £500 a month to costs, which couldn’t cover all your living costs even in a bedsit, meaning you have £1500+ disposable income every month, - which you say you spend mostly on clothes, entertainment and shopping. top of this, he has given you a car, buys you eg expensive costs, and offered to pay for half your dog’s vet bill, which you turned down. ie you are profiting both financially and in terms of lifestyle by being with him. You have also said that you aren’t good with money (which is also suggested if you have no savings and have to stick a vets bill on a credit card), so….
- you are definitely already being subsidised massively in enjoying a lifestyle massively above what you are contributing, despite up until now, not having children involved.
- you are unreliable with money and perhaps have always lived above your means, and he is perhaps afraid you will apply the same principles to his money?
- you agreed to separate finances via a prenup, but now seem to expect to share everything and are making assumptions that he will pay for stuff even when it’s your expense that you would have even if he wasn’t around?
- sounds like there are issues in the marriage independent of this, if he is suggesting sleeping in a different room?
all that being said, if he really said you weren’t equal because of the money, then that is really shitty. Or was he saying he didn’t feel you should have equal decision making power over how his money is spent? Those two things are very different.
and secondly, if there is now a child on the way then this changes everything. I think it is actually reaonsably fair that two working adults each live within their means, with the richer one paying more costs and providing more treats, without subsidising the other too much or merging finances. But having a child is a totally different thing. Now you are sacrificing earning power and career advancement, AND you have a huge joint expense in spending for your shared child. You have to therefore come up with a better arrangement that sees at least a portion of his money as shared, in recognition of your sacrifices and dependence for the sake of the family, and also an understanding of how the child should be paid for, which should be by him almost entirely in the case of massive income disparity.
if he’s not willing to have that conversation, then you have a big problem.
