Dear Eric: My ex-husband and I were on fairly even financial footing when we divorced. Our incomes were similar, and we split the assets almost down the middle. He was a lazy, selfish, philandering husband, but he’s a decent dad. Losing that 200 pounds of deadweight has freed me up to focus on advancing my career. My income has doubled, while his has remained relatively stable. He doesn’t know what I make now; I know his salary because it’s public information.
