Money in the relationship

I've heard that German men are stingy (or they call it women's independence), when a couple goes out to eat, everyone in the relationship pays for themselves. Or when they go shopping in the supermarket, even a drink is not covered by the man and they split the payment. Is that also true? I find that a bit weird as a woman and not so romantic. But I also see generous Germans who spend a lot on their wives. What does generosity depend on? Is it individual upbringing or different incomes or something. If you are in a relationship, what is the ratio of shared expenses? Is it 50:50 or 40:60 or...? How is it with you?

Summary: I have read all your comments, there are great couples who work well together financially. I sincerely wish you continued long love and all the best. I think the model with a percentage contribution is good, i.e. whoever earns more pays more. I think the three-account model is good because you keep your freedom for yourself. And no, women don't just take food, you can also take turns paying for food so that it doesn't seem so stupid to separate every penny when paying. And thank you for paying for drinks as well
