there's a context
It's all well and good to be independent when you both earn similar,
it's starting to be an issue when one earns double or more the other earns, and you end up with thread where one adult has nothing after paying share of bills and childcare, while the other is left with a 1 or 2 thousands of disposable money.
So not having "family money" is very very weird, the dynamic is all wrong.
If you like to be so "independent" that you can't afford a new coat or a pair of shoes after bills, but your partner is going away every weekends with their mates and just buying themselves a new car...good for you, but for most couples it's very wrong.
