I did nothing to upset her, had invited her over to mine with my other sister and my niece and nephew for some dinner. She said she would be coming in reply to my message inviting her. The next afternoon I got a message from her saying she wouldn't be coming as I don't want her there and as far as she was concerned she now only has one sister, niece and nephew. I replied with I don't understand,to which she called me a mini version of our toxic mother and a nasty lying cunt.
