(Hopefully) Stupid question. Do you have a safe place you could go to quickly with the boys?
Realistically, you can say that you don't understand things and that you want to be sure that you don't make mistakes with the biggest decision of your life. You wouldn't buy a new lawnmower without carefully checking your options much less something this significant. It's not just you two here. You both need to consider the boys and their future.
Also - it is the case (at least here) that an agreement where both sides haven't received independent legal advice is more likely to not hold up in court if circumstances change and it would cost both far more in legal fees unless things are done carefully. Lawyers love "kitchen table agreements" helps pay for their toys.
Because I always have the poorly timed joke there's the old one about divorce lawyer in office-towers. So they can see the boat they just bought with the fees you paid them (apologies to the lawyers present).
And - if 9:00 rolls around and he explodes - point to the door. And have a safe friend handy. Just feeling paranoid.
