We did not really do monthly but had an annual budget to talk about so we could agree on our values and goals. Early in our marriage, we checked in often and talked perhaps monthly or quarterly. Each bigger expense was discussed. In 48 years this is ingrained and we now only talk over pretty huge expenses and at least an annual review of our financial status. I get an income statement an net worth statement for the year from hubby.
We have met all our goals probably 4X what we thought was what we needed.
