Sonya Britt, an assistant professor who has a PhD in financial planning, says the top predictor of divorce is arguments about money, after studying data from more than 4,500 couples.

She said it doesn’t matter how much you make or how much you’re worth.  People argue about money at all levels.

“It’s not children, sex, in-laws or anything else. It’s money — for both men and women,” according to Dr. Britt.
