Also, the fact is he obviously loves his kids, so even if you have to take legal action that he CHOOSES to define as "adversarial", he's not going to abandon the kids. He still wants to spend time with them. He may get angry with you for a year, yes. But he likely will not abandon his children. And if he's that kind of guy, YOU can't change that anyway. I'm just saying don't let him dictate whether or not mediation is what's "best" for you. Especially if he spends all his time at work talking to paranoid, post-D, bitter dudes.
