So my wife and I have a joint bank account and joint fiances, all our money goes into and our of joint accounts. This seems to me entirely normal; the vast majority of our expenses are shared/family/kids e.g. mortgage, household bills, days out with the kids, grocery shop, kids clothing, kids clubs etc. Obviously there are occasional personal things (clothing, nights out that only involve one of us) but relatively minor in our expenses. It seems genuinely insane to me that we would keep seperate accounts then each pay half of the joint expenses - the admin would be a pain and we're married - even if we get divorced our assets would be split not on the basis of who owns them but as splitting things we own jointly.
I genuinely can't see any other way of looking at things but there is a theme in MN (and elsewhere) that suggests others view things differently. The recent example of this was a thread where someone said "I don't know why I bother working, my income barely covers child care" and numerous people responded "doesn't your husband pay half the child care". That question makes literally no sense to me (for the reasons outlined above). Can anyone explain what I'm missing?
