My divorce with my ex wasn’t really related to that. After about 20 years of being a normal member of society, He developed a drug addiction, and decided to devote his life to getting high. He quit his job, cashed out his retirement, and spends all of time acquiring drugs. He is currently homeless. He told me this is what he wanted to do with his life now, I tried to help him get help, but this is what he chose. I have to respect his choice, but it wasn’t the life I wanted for myself, so I wished him well and moved on with my life. I think he’s afraid to grow old, he watched his mother get real sick with dementia and didn’t want to experience that, so he’s hoping to spend his days in oblivion until he finally over doses.

He and I had a pretty happy marriage for about 20 years. There were many ups and downs for us both financially, and we are both there for each other. But overall I made about triple what he did. It was never about money for either of us, we were quite happy together. Certainly he didn’t have addiction issues when I met him, that didn’t come out until the last few years. It took well over a decade before that behavior took hold.

I’d like to see this study you are referencing. And I would like to mention correlation does not imply causation. If women are unhappy in marriages where they make more than their partner, it may be more about their partners lack of ability to function, perhaps the lack of income is an indicator of greater issue with the partner and that’s causing unhappiness?
I mean yes, there do exist hypergamy, but mostly women want good partners, and that’s not simply about being rich.
