Monthly Expenses Update

When I was still working and paying for all our monthly expenses, I know how much is the fixed monthly expenses. After not working for more than 2 years now, I really have no idea what is our current monthly expenses. I handed everything to the sole income earner of the family; my dear hubby. Unfortunately, he did not keep a record on it. He does not even know how much we need to spend for term life insurance every month. He sees the credit card bill, he pays. Looks like it is high time, I take over the finance dept. ;)
