Reappearance of distanced siblings

My Father was diagnosed with VD with onset AL 4 years ago. I took over as POA due to a broken unrepairable bridge between my Sister the former POA, and Dad. I've learned so much about their former relationship in the last 4 years and frankly, I wish I woud have found out sooner in order to rescue Dad. She kept him in the dark about his diagnosis while meeting with his Drs without him. She became on a first name basis with anyone within his care group.

I've had to explain to him his diagnosis and have had to find him an all new care group as the trust he had is now lost. He has a great team thanks to the VA. His new team talks with him and he loves being involved and included.

While still working 3rd shift, I was his primary care giver. I would go from work to his house. I fixed him breakfast, walked and fed the dog, give him his meds and began laundry and lunch. I would go home with the dog to nap or run my errands and return to his house after about 5 hours and leave for work from there. My off days I would stay at his house and not go near mine. All of this with no help. I would call repeatedly with no such luck. All I heard was empty promises and unanswered voicemails.

I've had to make the decision to move him into AL at least until I can have the house made more accessible for him. The Drs recommended him for AL after an accident at home. I'm using the renovations in my favor. Dad knew it was either AL "a special apartment" or 24 hours care. He is too stubborn and independant for 24 hour care. I worked with both the VA and another search group and compared. I spoke with the powers that be for the financing. It was a rough move in since it's just me. I purchased new and had some of his furniture brought into his new place, I shopped from the list that was given and have set the place up again, on my own. I was lucky enough to know an old friend in the moving business who helped move and assemble what neede to be assembled.

Dad is really thriving there! The Drs love how well he's doing. The only extra stress I have now is taking care of his dog. I visit with him 3xs a week and even have a sleepover on my first night off. He loves that! I have also brought in aides for 20 hours a week. They are there at least 3 days and sometimes 4 depending on his and my schedule.

Here starts the problem: The night before his discharge from the hospital into AL, his neice came to visit and started such a scene that the nurses called the PD. She was telling him he needed an attorney immediately because she was certain he didn't have a signed POA and he needed legal advice now. She had him convinced that he was being put in a mental hospital in order for me to steal his money. She erased his information on his patient board and wrote all this bs on it. She even wrote a list of people for him to contact. I didn't even receive a call from the hospital. I was surpeised by this when I went to pack him up . I had to prove myself to the PD even though all they had to do was look at his chart. I took names! I then tod the officers to escort her out and that she is to not return. Dad's attornies sent a no contact letter and filed for a protective order. Fast forward to the following week.

Dad's other 2 sisters whom he hasn't seen in 5 years, appear at the AL. I had not informed anyone of where he was going until I knew for sure he would stay. They both were depely offended that they weren't part of the decision. I'm sickened that the AL opened Dad's door to let them in with no check of IDs. After the first visit, they called his attorney claiming he was being munipulated into being there. He wasn't getting the proper care and I had tricked him into going so I could have all access to his money and that I couldn't be trusted. His attorney called me fuming. He said the office was getting call after call and I was tild to get my ducks in a row. All because they found him curled up in bed sleeping in a locked bedroom late in the afternoon. They visted again a week later and uped their game by asking staff and his aide if they had met me and what they thought of me. They questioned why he was there and if he was happy being there. The AL even called to tell me that had to stop. I've asked through the one sister's attorney, to stop the visits. Dad is too confused and aggitated after their visits. He doesn't want to lose his new place and doesn't like how they are bothering the staff. He can't stand what they are saying about me. The 3rd visit, I interruoted and they quickly tried to find an excuse to leave. I learned after they left that the visit was just as hard on Dad and made the aide extemely uncomfortable.

I've responded to the sisters very nicely and to the point about his diagnosis and my decision process. I expalined that if they were there when he asked for them, I would have included them in my decision. I told them the sadness comes from the guilt they are feeling for neglecting their brother and there's no reason to punish me. I've blocked their numbers because one of them calls him 8-10 times a day up until 2a.

Any suggestions on how to make the visits stop? I can't handle the aftermath. I don';t want a legal battle or any family upheavle. Especially since Dad's short term memory is gone. I have sent messages to his attorneys to help make the visits stop with no response. I've even spoken to one of their attorneys that just so happens to be Dad's neighbor. He's seen Dad's progression and has stepped in to help me with various car help and yard work that Dad can no longer do. I see that as a plus.

I'm at wits end.
