My husband and I have been married for 24 years. We have always had a joint account. We have always considered it "our" money. We have taken turns paying the bills and managing the budget. We pay our bills 2 times per month and usually discuss upcoming issues at that time. We also try to look ahead 2-3 months, so we can try to anticipate bigger expenses, etc.
The best advice I can give you is to commit to not blame each other about money problems but work together as a team.
Good luck!
