Most men can recover from the financial devastation of divorce. Heck, they can arguably recover more easily than the average divorced woman.

It's the social aspect. After a certain age, older, single men are viewed as creeps or even potential predators and ped0s. Older, single women are not viewed as creepy and they're not excluded from polite society.

Also, there is the dating aspect when you already have kids. Stepdads are viewed more positively than stepmoms in our society for whatever reason. There are also fewer expectations towards stepdads than towards stepmoms. If a stepdad is not an abuser or a ped0 it's typically viewed as a win. He doesn't even have to do anything. For stepmoms there are more complicated rules, especially if the baby mama is still in the picture. Stepmoms are expected to play mommy and love the kids as her own but also never overstep. How many women are going to sign up for that? I have a feeling this is a big reason why many divorced men become deadbeats.
