Splitting hairs is exactly what it is. When my ex and I divorced, I would have been perfectly happy to never have to speak to or see him again, but I understood that I needed to maintain a cordial relationship with him for the sake of the kids. Lately it seems that I've seen more parents who would rather waste all their time and energy on doing things they think will hurt the other parent and giving no consideration to how it affects the kids.
I also don't think a lot of people understand that judges generally don't want to waste their time refereeing every little detail of custody & visitation agreements. I've seen people go back to court pretty much annually over the stupidest little things. Personally, I hate courtrooms and have never particularly enjoyed any time I spent in one, whether it was as a witness, juror, or obtaining my divorce. I can't imagine wanting to hassle my ex enough to drag him back into a courtroom every year!
