The best thing I did for my relationship with money was form a zero based budget. It let me responsibly decide how much I could spend on frivolity without sacrificing big picture goals. It’s a very useful exercise, i highly recommend it.

There are several software options that can help you set it up - or Excel. I use YNAB4, but they don’t sell it anymore. I highly recommend it if you can find a copy online

There are a few similar systems I haven’t tried

r/actualbudget r/AspireBudgeting r/Budgetwithbuckets r/everydollar

The new r/YNAB is subscription based and IMHO, overpriced. There are threads there about alternatives from time to time
