My ex-wife was similar, but I don't know your whole situation.
At the time, I worked as a diesel generator technician, and then later in the marriage an industrial automation engineer. I had at one point somewhere north of $30k in tools. Mixed brands here and there, but the tools made us well into the six figures of income every year. But every damn time I bought a wrench, a socket, a new set of meter leads "YOU DON'T NEED THAT!!!!" even though it was exactly what I needed and our family needed so I could provide a higher level of income. She meanwhile purchased Coach and Michael Koors purses two and three at a time, never carrying one more than two weeks before relegating it "out of season" spending exorbitant amounts of money on takeout food for lunches and something called "rustic cuffs". She was employed as a receptionist and made <$12/hr, she was chronically late, took long lunches, and left early. So her 40 hour paycheck would end up around 30 hours on average, minus taxes, and her 401k. We would have been money ahead for her to not work and keep the miles, maintenance and fuel usage off the BRAND NEW F****ing car she had to have while complaining when I wanted a new truck for my hour long commute (one way)
.....rant over?
Long story short some of us can feel the pain, I couldn't solve the issues without leaving the marriage, but we had many more issues than just the money aspects.
I have no idea where I was going with this?
