My stepdad does not want to be with my mom anymore because "he has his own life to live". He is threating to put her in a home so he can "live his own life". She still has all of her facilities. He is extremely abusive to her and is trying to make her dementia advance faster by the abuse he gives her. She does not want to go in a home. She wants to stay in her own home. Does she have any rights?
