Similar thing happened to me . I had a good friend for years . I looked after her when she came out of hospital, washing cleaning ,shopping , cooking her meals . When I had major surgery she didn't come to see me in hospital . When I got home, I had to stay upstairs for a while , (not allowed to use stairs) . She came to see me to borrow something .I asked if I could ask her to do me a favour and warm up the odd ready meal for me in her oven when she was cooking , (not every day ). She said she was too busy , and that I should carry my microwave into the bathroom. I introduced her to a women I know. This women was very wealthy. Suddenly I was dropped .She said I wasn't able to go to interesting places ( expensive restaurants and spa treatments) because I couldn't afford it . She even put a really nasty post on Facebook about me thinking I wouldn't see it , but a friend told me. I'm actually glad a few years on that she dropped me as she was a terrible snob and self centred.
