"There can be no romance w/o finance" -Star Jones.

I had a wife. We kept separate bank accounts split the bills 50/50. Things worked fairly well. (We were middle-class childless couple in major city in a house MCOL)

So the way I understand is a married couple is supposed to have a joint account and joint credit cards and joint cars and all that co-mingled finances stuff.

How is committed relationship finances supposed to work??? How is it supposed to work if one spouse/SO doesn't work to take care of children????
