I have a list of what my husband and I spend on a monthly basis - it is called a budget.
Our budget includes mandatory household costs (e.g rent, heat/water, food, etc).
I don't necessarily itemize every single thing that I spend on my budget - say, $0.70 for toothpaste, $4.50 for a DVD rental, etc).
It is not necessarily unusual for you to itemize every thing - in fact, some people find this very educational and helps them stay within their budgets.
