Hi Mike,
It isn't as painfull as it sounds. Its more of a pain in the butt. I (we) had to take a "parenting class" when my son was born. I wasn't married to the ex, he had no custodial rights and there was a hefty ro in place at the time, so it was more bizarre than anything else. I still don't think the ex ever complied.
The focus is more on making sure the kids are ok and not in the middle of anything. I remember the class was divided men/women so it got a little heated at times. Lots of emotions coming out. Just sit in the back and do the time to get that certificate. It's more focused on "statistics" than anything else.
Good luck...its going to be ok.
