My 8 year old lives with me & we are just about to move in with my partner after living alone since splitting from my childs dad. My childs dad is a bully in all respects but particularly cyber bullying. Im going to inform him we are moving in with my partner & he knows my partner first name but how much personal info (if any) do I legally have to give my ex about my partner? Spacifically do I have to reveal his full name? I am concerned he will use this info to start bullying my new partner.
