Moving decisions?

For the last couple of years, my 85 year old mom has called me every 3 or 4 months and said she wants to move from her apartment to an independent living facility where she lives, but then changes her mind. Up until a month ago, she would then change her mind and decide to stay in her apartment. About a month ago she decided to move, the unit she wanted was available, and so my husband and I spent about 10 days, packing, going through her things with her, selling furniture she wanted to part with, etc. She seemed to like the new place, with a few exceptions. For example, she moved from a 2 bedroom, 2 bath apartment with a patio to a studio that didn't have a patio but did provide meals, and most importantly, that she picked out. She doesn't like the people in the the independent living facility and didn't want to feel like she was shut up in her room. We live about 500 miles apart and I've visited about every 3 or 4 months the last couple of years due to hospital stays/health issues she's had, to help her out. After living in the new place for 2 weeks, she called today and said her previous apartment is still available so she's moving back, as soon as possible and signed papers there today. It is her decision, and she didn't ask for any help or money (we had provided several thousand for the previous move; we were happy to help), and I didn't offer. I'm concerned that the same issues that made her want to move before are unchanged and she doesn't see as problems, but will complain and want me to solve. She really values her privacy and access to the outdoors which she'll have with her patio in her previous apartment, and I get that. I guess I'm just venting as we busted our butts and she's tried the new place for a short while and changed her mind, which is her right. There's no arguing with her or even disagreeing and it is her decision. She's having short term memory issues and sees herself as much more physically capable than she is. I'm retired and so can be flexible about visiting; my husband is still working and hopefully will retire in a little over a year. We have no plans to move anywhere for as long as we can, and as harsh as this sounds, and won't move where she is, given the history of her being domineering, bullying and sometimes just mean in recent years to me, my husband and two daughters (grown, married, etc). There are no other family members that can help, as I am my mentally ill brother's guardian and my dad has passed away several years ago. I can continue as we have, doing what I can from a distance such as ordering groceries weekly, coming up with ideas to solve things, which sometimes she likes or as often as not, criticizes, and visiting to help when she has medical issues. Last year, she thought about moving back here, so I looked at apartments for her, but then she changed her mind. Like I said, this is her decision, but I guess I just worry that she needs more and more support but won't accept what's available, except she did accept temporary home health care following a couple of hospital visits in the last couple of years. I don't know what to do or that I even can do. Thanks for reading and letting me vent.
