My Mother's Friend comes and spends 3 to 4 nights from out-of-town with my Mother. She refuses to accept my Mother's dementia diagnosis, along with no alcohol, and keeping me in the loop of what's going on when she visits. She drives my Mother anywhere she wants to go. And, my Mother spends money on things she doesn't need, or over spends, period, and the friend doesn't respect my wishes as caregiver, daughter, and D.P.O.A., and told me in so many words to butt-out, and that she isn't friends with me, but my Mom, and to leave her alone, and to quit telling her what to do, and her friendship is with my Mom and not me. My Mother is a recovering alcoholic since the beginning of this year. And, she has dementia, and she cannot drive. She has, also, been diagnosed with bipolar and major depressive disorder. My Mom has a lot of problems with managing money, and I have to help my Mother with everything that requires making sound decisions, and help keep her away from alcohol. I, also, drive her everywhere, take her to all medical appointments, make all financial and business decisions. I am responsible for my Mom. This friend is an enabler, and she doesn't respect me, and I don't want her around my Mother driving her all over the place, and spending several nights and days at a time. Her last trip, she smashed a laptop with a hammer and threw away, took my Mom to a new hearing specialist, where my Mom bought new hearing aides, took her to buy a walker (my Mother hates, and i had to buy her another one, and she likes it) tried to get my Mom to buy her relative's dog, and my Mother lies and acts like an insolent and insidious teenager, and then says she doesn't remember. And, this friend takes offense with me and doesn't understand that I need to be kept in the loop, and she won't follow my guidelines concerning my Mother. And, once she leaves, I am left to pick up the pieces, and it is awful, and she just is not welcome. What legal rights do I have to tell the friend that she cannot visit and/or spend-the-night? She spends 3 to 4 nights at a time. Just the negativity she brings and the stress. It is awful. And, she is a bad influence. She's rude, arrogant, disrespectful, and I am trying to keep things positive. I don't trust her or my Mom, especially, when they are together. She is on a lot of pain medication, too, which I have a problem with when it comes to her driving my Mother places around town, too. If I tell her she has to butt-out, or that she is not allowed in my Mom's house, or not allowed to be with my Mother, I want the law on my side if it comes to me having to make this stance with her. Can anyone help advise me on how to handle? And, if it doesn't stop, what legal recourse do I have to back up my words if she doesn't listen and stays away?
