Should I feel guilty for not wanting my Mom to move in with me and my family?

My mom and I have always had a rocky relationship, but recently she had a really bad car accident that left her in the hospital for 2 1/2 months. During the first few weeks my mother cried a lot, felt really sorry for a lot of stuff and seemed broken physically and mentally so I offered for her to move in with me and my family (husband & 14 yr old son). My daughter is 20 years old and already out of the house. I live about an hour away from town in a very small town, but would drive in daily after work to see her. Through my mother's recovery, she began placing more and more responsibility on me and would call me at night saying the nurses wouldn't give her the right meds and to call her doctor. My mother had the doctor's number right on her nightstand, but when I told her it would be better if she called the Dr herself in case he had questions.... she got mad and said "Nevermind," and hung up. I set up plans for my middle brother (whom she currently lived with in a mutually toxic relationship) to keep her cat and belongings while she was in recovery until she could decide what she wanted to do to which he agreed. No sooner did I hang up she called him and faught with him, threw him out of the hospital when he came to visit causing him to no longer want to keep cat or belongings. He said he was moving out of their rental at the end of month. This now meant that I would have to go to her house, pack all her belongings, furniture and move them to a storage unit. This made me mad because of her actions and fighting I would now have to move her stuff now. While I was at her house, she kept calling and asking questions about what I was packing, did I get this or that, etc., I finally told her I'm busy and trying to get this done I will talk to you later. Her storage unit was only so big so she told me to leave some items behind and mentioned what meant to most to take, but in the end she complained about how I didn't get this or that. Later she thanked me, but it was too late and I felt very unappreciated. My mom's nurses would call me and say that my mom said she was moving in with my brother and his girlfriend - first time I had heard this, but then would act like she's coming with me. Nurses also would call me and say, "Your mom said you have questions for me, when I didn't." I mentioned possibly building a cassita for her in our back yard and she said, "Well, I'd like a 2 bedroom...." When I told her it's one room with bathroom she said, "One room." I had to reassure her that she could come in main house whenever she wants. Whenever I would call my mom on her negative behavior or her all her drama could not come to my home and that we live a peaceful life, she would blow up, scream at me and hang up. I began to see all the things in her I didn't like when I was young and it appeared to me the better she got the more issues came up and drama. My husband even went by himself to visit her and explained that the drama effects me negatively and that he is concerned about his wife and that this couldn't continue. She reassured him that the drama would stop and apologized. She even called me and told me that she loves the way my husband loves me, but it wasn't long before more drama came. I finally went to the hospital and told my mom that I felt that it would be better if she went with my youngest brother and she said she agreed, but then got teary eyed and acted like she wanted me to leave. My mom's phone calls to me became fewer until the day she was discharged from hospital. The day she was released I didn't get any calls. I found out through family that things with my youngest brother didn't work and they asked her to leave, so she was now at her sister's house. My mother finally called and asked me about her car insurance and her settlement for a new car. I explained how that would work and asked her why she hasn't called me. She immediately deflected my question and changed the subject. I brought her back to my question explaining that she hasn't called, why and explained that she knows that I worry about her. She said "Talk about what?" with attitude. Then she goes on to say "You have already done the worst thing to me, but never again." I asked her what? and she said "I had to take a bus home from the hospital to your brothers. My brother doesn't have a car and she never called me. She then says, "All I need from you is for you to get my insurance money and find me a new car. Then I won't ever be a burden to you again." I got mad and tried talking to her that she's not a burden, and plead my side, but she rebutted everything. The phone call ended with me saying, "I'm not playing your game." and hanging up. Now I feel guilty, like I'm not coming through in my heart, but my mind says RUN!
