(((BobbyJ))) Please remember that people are looking at HIM because of HIS actions. He is making a paranoid, out-of-control, fool of himself, and the people that you both know can see it.
I do not know what the law requires if he refuses to sign the divorce papers, but for your sanity, I recommend having your lawyer talk to his lawyer or him directly.
Keep your head up, Bobby! You have done nothing to be ashamed of......!!!!
