I don't know anything about ROs...are they public knowledge if he doesn't violate the terms?
Anything that makes you feel vulnerable...don't do.
The shark is on your side. Better than on his. You have your children to protect.
The reality is that many of these guys find a new relationship really quickly and then try to walk away from their previous lives like it never happened.
He may not, but if he does, better to have your interests protected.
