You have my sympathy OP. I think it's possible that some people, as they age, undergo personality changes and their worst self emerges. My mother moved to a block of retirement flats in her 80s, and to all intents and purposes she was very happy there. I do remember her telling me about a couple that got together whilst they were living there. The male partner, according to my mother was friendly, outgoing and well liked by all but morphed into someone quite different from his original self. It seems that his new found love interest cranked up a side of his personality that was more akin to her own, miserable, prone to outbursts of anger at minor issues. My mother who had an abundance of common sense often said to me "not a good idea getting together with a new partner at that stage of of life" The female side of the relationship was 91 apparently to his late 80s, I mean just why would you at that age ???
I'd give it a bit more time leapyearnan, moving is such an upheaval but of course it's essential you're happy wherever you choose to live. Good luck with whatever you decide.
