Me - 43
I agree with Stronger.
XWH used to handle all the finances even though I worked full time as well. We were always broke.
When we split up, I was worried that I wouldn't be able to make ends meet, didn't know the timing on which bills were due when, etc.
I sat down, put everything into a spreadhseet and budgeted out the next couple of months.
Imagine my surpise when I not only got bills paid on time (or early) but also had money left over!
It does get easier with practice.
