Elderly friends care?

I have an elderly friend who is 82 years old. He never told anyone he had epilespy, but he has told me that he has had strokes. He wouldn't let me call anyone. Finally, he had a seizure and possibly a mini stroke. For two days he was on the floor crawling around and the neighbor found him. When I found out through the preacher that he was in the hospital, I called him. He had somehow lost his memory. I thought maybe his memory was going before he got hurt, but I couldn't tell to well over the phone. He's always been paranoid of people trying to steal from him. I was able to get the phone number of his elderly sisters who are half way across the country; we are in Washington though. He told me not to call his sisters but I felt it was my duty. He went into the hospital when the next door neighbor found him. He lives a ways from me. Now he is out of the hospital and in a rehab center. This friend of his has a husband who is an attorney. She came over and did a will for him while he is still in the rehab center. She is charging him $500 and she told me that she wants to become his guardian and put him in a rest home and take control of his finances. I'm concerned that she is after his money. I called this sisters and told them I knew of a place that is way cheaper than the rest home, but he may have too many problems for this place. Next, I told his sisters that my daughter is a NAR and could care for him if he could get a place in town. My daughter doesn't drive and must take the bus. He lives way out in the country when he's not ill; before he went in the hosp and rehab. Next, I told their sisters I could get guardianship of him and bring him back to them by driving him across the country. I have also suggested to them that they have children or grandchildren take care of him. There are so many options, but he won't take anyone's help, not even let anyone change his depends. He can't remember anything hardly. I just want him to be safe, cared for, and loved. We have square danced together for 6 years. I don't know what to do for him and his sisters aren't quite sure what to do either since he would never move back east where they are. He never wants help. What can I do? I don't want to marry him or things like that. I can't care for him right now. I have a 14 year old son and three adult children that run me ragged; the oldest is 31. I'm also going to college after all these years finally. Something I've always wanted to do. Even if I quit college, I think his care is beyond what I can physically do since I've broke many years ago. He is wheel chair bound since the mishap. He is finally standing but can't remember when to use the restroom. Any ideas, advice, or anything. I refuse to take him outside the rehab. I think he might fall or try to not listen to me to return to rehab or something. I did buy him a cell phone card the other night and some other things. Then he lost his cell phone or someone stole it at the rehab. I told him maybe he ought to just use the phone in the hall for patients until they find his phone. I'm also afraid he may loose it again.
