But all those things can be put into the prenup. Custody, ugliness with rumors, bringing new romances or mistresses/misters (i don't know what you call the men) around the kids...it can all be addressed with whatever consequences you see fit.
Lol and all those things can be contested. It doesnt matter what pre nup you sign, you can still go to the courts for custody, and in the process of gaining custody, the mudslinging begins. The rumours too.
