I'm just wondering (nosey even) whether you share money with your partner?

DH and I have always had 1 bank account which all money goes into, we've never ever had that's my money dramas. However, some friends I have spoken to don't share money or bills with their partner. Some have to buy groceries and their childrens needs from their FA because hte partner pays bills from heir own money. I find it a little strange but only becuase that's not how we do it. I have no judgement on the subject, I just find it interesting.

How do you do it?
