I sure hope someone has the guts to answer this question; no one has when I asked it in my OP.
The long and the short of my previous post was the fact that I was getting frustrated with my wife's propensity to spend the majority of what she makes at her job, primarily on things that support her own happiness. I make significantly more and cover the vast majority of the things we actually need to live. I split our finances years ago because her spending was causing financial issues. Money for rent being spent on horse boarding and similar.
Many of the responses I got functionally boiled down to me being an a-hole for doing what I had to do to make sure we could pay our bills. And I should be making sure that my wife is happy.
So here is my question. What if the gender roles were reversed? What if, as it is now, we both had degrees in fields that would net each of us, conservatively 80k a year, 160K together, but I decided to take a job that pays 35k a year because it makes me happy. While at the same time wanting to spend on myself, like we are making 160K together.
I could be wrong, but in that situation, I would likely be called a deadbeat husband. I would be told that I need to get my act together and man up.
tl;dr: Is the only reason that I have to support my wife's happiness at the expense of my own, because I have a pecker?
