He actually sounds like my husbands ex wife. There is whole ton of people with restraining order against her, that scary she is. She recently once again physycally assaulted my adult stepdaughter. But her behaviors originally started with just berating people like your husbsbd does. Then it escalates to dangerous level. She also accused multiple people of multiple things (all unsubstantiated) like rape or molestation or assault etc never any proof

Be aware that your husbsbd will get worse too

Keep your distance from him and get out now
