> you only ever stand to lose half your resources
Not true. You can lose half your current assets easily, but possibly more.
Then you likely need to pay alimony for many years, which if you add it up might be.. pretty much the other half, depending on the situation, and maybe much more.
And that’s before talking about child support, which can be gamed, because they can argue for higher custody percentage in order to extract higher payments from you. It’s so common it’s basically routine.
