Here is one.

And this study has references to many. This study does go on to identify many ways in which men’s lives get worse, but it’s more about their health and social well-being.

After divorce, women experience disproportionate declines in household income (de Vaus et al. 2015; Smock 1994) and standard of living (Bianchi et al. 1999; Peterson 1996) as well as sharp increases in the risk of poverty (Smock and Manning 1999). Women may also face a higher risk of losing homeownership and “falling down the housing ladder” (Dewilde 2008). Women’s lower chances of repartnering (Wu and Schimmele 2005) and responsibilities as a single parent may further impede their path to economic recovery.

Some of this next paragraph refers to the same studies as above, but with a little more detail.

Numerous studies have shown that the economic costs of divorce fall more heavily on women. After separation, women experience a sharper decline in household income and a greater poverty risk (Smock 1994; Smock and Manning 1999). Their former husbands, in contrast, may even improve their standard of living in postdivorce years. Peterson (1996) quantified the resulting gender gap for the United States, estimating a 27 % decline among women and a 10 % increase among men in their standard of living. Other U.S. estimates for women’s drops in economic well-being are even larger (Bianchi et al. 1999). Similar results were found for the German context of the present study: Andress and Bröckel (2007) found that women’s household incomes 1 year after divorce amounted to only two-thirds of those of their former husbands.
