Think he is entitled to know everything about everyone? When you don't tell him what he wants to know (personal information) he keeps pecking and pecking like an obsessed woodpecker. Does he not understand what none of your business means? Does he not understand that personal information is personal? Or does he want 'the goods' on people so he can use it to ridicule, hurt, and harrass them? I think that is the reason. When you don't tell him, he obsesses about it. Probably keeps him awake at night.
