Given the reality of brutal divorces, custody losses, asset seizures, suicide, and criminal escalation that come with modern marriage, if a guy wants his own kids and a family, what kind of options are available to him?

I don't know the details so I'm asking here. Is there some kind of structured agreement that wraps up an iron-clad pre-nup, a co-parenting agreement, a mortgage, estate planning, income splitting, and some of the other benefits of marriage, which takes some of the downside out?

If a generation of young men in north america recognize that marriage is a shitty deal, there are going to be some big social problems. What does a good deal look like?
