Maybe in a “partnership” you don’t need to ask a “partner”.
But in marriage you don’t have “your money” - you are both on the same team, so all money are shared.
If you spend $1000 on something random, that sets your team, your family, back of its common goals - house down payment, vacation, etc.
I am in a long marriage,we each have our own money and joint account money. We are both in the same team and can spend our own money. Each person has the same percentage of take-home to spend as an individual.
This is just you having "extra" money. I guess it's a demographic thing but do you (and everyone else) not understand that over 50% of people (in the US at least) don't have "extra" money. The money they make is already allocated before it's made, any sort of "extra" spending goes on a credit card or forces some other payment to be not made on time, often incurring fees. In some cases that money would deplete a small savings balance.
This is pre-covid numbers but 69% of Americans have less than $1000 in savings. 45% have no savings, and roughly 30% spend more than they make each month, accumulating and juggling credit card balances / short term loans.
I'm from a poor area in the US and most people have $0 "extra" money. As an example my high school 10 year reunion was a few years ago and the target goal was $20. Even with a year's notice most people said that would be too expensive and they wouldn't have it. ($40 per couple).
We had multiple fundraisers to try and get everyone to participate. The fundraisers were everyone buying extra chicken wings with their food stamp cards and giving it to a local restaurant that cooks them and sells fundraiser plates and a car wash sponsored by the bowling alley that gives a free game to anyone who gets a $5 car wash.
How long can you continue to spend more each month than you make?
I don't fully trust that story. Maybe many of the people who have "no savings" have a mortgage to pay off? Technically they have a debt and all spare money goes to the bank, but really they own a house that is worth more than the debt?
In such cases I'd say it is more of a mindset issue.
I don't get the quotes. Not sure whether you're mocking or hinting at my use of the word partner as being incorrect in this context or you are downplaying the seriousness of (romantic) relationships outside of marriage. Well, if it's the first, indeed there is the name of such "partnerships" it's officially called a domestic partnership and legally not very different from marriage in most secular states in the western societies.
If it's the second one, it may come as a surprise, but you you don't have to go to the church, even in front of a state representative or throw a big party to start and maintain a normal, pair bond based relationship or even a family.
And I'm pretty sure that most people who end up marrying, start with such "partnerships" and only "upgrade" when they feel that it "works". Which also means that they'll set most of the rules before the act of marrying. It's only a guess, but it wouldn't make sense to make too big changes compared to what you have tried, what worked and what you've probably grown to like. I'd also guess that it's the same with money things. At least it should be, because it's said to be one of the few that can cause serious disagreements between partners.
Anyway, to put it short: different people require and like to maintain different level of independence (or the illusion of it, doesn't matter). Also, $1000 can be a large sum for one family and a smaller one for the other, so it's actually pretty hard to even gauge your opinion. E.g. I live in Eastern Europe, work as a software consultant and while $1000 is about the average monthly salary it's just a fraction of mine and my partner would never see it as a setback if I spent that amount on myself because I just felt like.
Of course, if we have common goals then you should not endanger those without discussing, but I wouldn't like to be in a situation where basically 100% of my earnings are accounted towards a common goal. That's just too much stress. Then you either making too little (which is very stressful) or have very stretched goals. And while it sounds almost the same, the difference is that in the second case you do have a choice to make. And it's better to choose a more relaxed set of goals and life. Maybe that 2 stories house in the suburbs or that 2nd car, etc. isn't worth it to have to beg your partner to blow $300 on a more expensive laptop. Or even just to have that thought in the back of your mind.
