SAF -- If you go through the courts for your divorce you can say goodbye to privacy and your unfettered right to parent as you please anyway, as the courts will decide, maybe with input from you, maybe after mediation, maybe not, how you and your children will spend your lives until your child reaches legal adulthood. Basically, your life is governed by the court until your youngest child turns 18 or 16 or whatever majority is.
I am very familiar with serial litigants/frivolous litigants (that's what you are thinking of?) -- my exH, a lawyer himself, is one. I am currently facing my fourth motion for contempt of court in two years. He has threatened me three additional times, once a few days before Christmas while we still had a temporary visitation agreement, and he even threatened our oldest DD, aged 20 at the time, with a motion for contempt, because he thought she had been rude to her grandparents. It's his little hobby, and he is seemingly able to take an unlimited amount of time off work to attend to court dates, file his stupid motions, etc.
Because I couldn't afford the sort of psychiatric exams for exH that I would have had to pay for if I had opted to contest his demand for joint custody, I am saddled with an angry lunatic whose mind is toxic to facts and hermetically sealed against reason and who wants to have me sent to jail, for the next 8 years and two months. That is why I think everyone should have to undergo a psychiatric exam in cases where custody is contested, and the cost should be borne by the state. Too many women are not able to afford the experts necessary to rid them of the sort of man I am dealing with. I am not alone either, sitting on the public benches waiting for parties represented pro se -- lots of other women in the same boat as myself, with exHs wearing nice suits acting all civilised and presentable in front of the judge.
