Congratulations on crossing the 50K mark and your anniversary!!!
I know different things work for different people, but I keep a small notebook in my purse and write down everything I spend. I "budget" for fixed expenses - i.e. mortgage payment, car payment, cell phone bill, insurance, etc. In the same notebook, I write down all my income for the month. At the end of each month, I subtract all of my expenses from my income and this is how much I can save or pay towards debt. It's very old-fashioned, but it's worked well for me over the years.
