I am so sorry for you @Justthe2ofus2007 where does your husband fit into this escalating situation? Can he not contact your in-laws (HIS family) and tell them in no uncertain terms to mind their own business and to NOT contact your mom in any way, shape or form? I would definitely contact the police, as the threat of using Facebook or any social media to threaten you, blackmail you or try to ruin your life is Cyber-bullying. Big hugs and my best wishes to you.
