GM, my ex once told me that "marriage is just a piece of paper" and more recently "contracts are just guidelines." Some people have no reality based thinking when it comes to such things. But like all contracts, they are only as good as the enforcement. Because that's what a contract is really for - to create stipulations for how things will work and penalties if they are not adhered to.
Your L is likely very good at negotiations. Like all negotiations, you can reason with anyone provided they are rational and are willing. If they are not willing, then you have to rely on the process and the laws.
Divorce will change your lives. It already has, as NLW pointed out. The divorce is one more chapter in the book.
All that said, I suggest you continue to look for ways to mediate. It seems to me that you don't want the divorce and may be working against it in some ways. I could be wrong. I wouldn't blame you either way. But it may be working against you getting things settled.
I can tell you that if you're afraid of what might happen if you say what you think, it's a sure thing what is happening will continue if you don't. It may continue if you do, but you'll at least have tried. There's nothing to fear in this. You'll be fine and will be better than you may think. Certainly nobody wins in a divorce, but it can be a big deal or it can be one more point on the journey.
You can thrive regardless of the curveball. You will have to look for those opportunities to do so.
Peace, AJ
