My brother left his wife a month ago and moved in with me and my boyfriend, and she has been demanding he return home. She tells everyone my 11 daughter and I are on drugs and her kids cannot be around us. She went so far as to call the police on my boyfriend and tell them she thinks he is sexually abusing my niece. This woman is crazy!! She has completely cut both her family and our family out of the kids lives. She calls the police on everyone and files some kind of report stating something happened with the children. My boyfriend is now heartbroken and scared. He has never even been left home alone with my nieces so there is no truth to her story. My niece admits my boyfriend never touched her . Do we have any rights?
