I've namechanged for this as it might make me identifiable.
I am friends with a group of mums from my DCs school. One mum in particular is very hard work, and gets very catty and nasty about others, with much foot stamping if she cannot have her own way. She falls out with people on a regular basis. Everyone seems to know what she is like and moans about her a lot.
About a year ago she got very cross with me as her DD didn't get invited to my DD's party. The girls don't particularly hang around with each other at school, although they did when they were younger, and DD only had a very small party at home with 3 friends invited.
Instead of talking to me about it, the mum phoned me up and was utterly vile to me on the phone. It was like a poison pen letter in phone call form. I tried to explain that it was nothing personal and that DD had chosen 3 friends only , but she just gave me an earful of abuse and told me not to speak to her again. That night, my new car was keyed in my driveway. As this woman had talked before about cars that she had keyed in the past I concluded that it must be her. She has since snubbed me and refused to talk to me, although does make horrible comments loudly in front of me.
I have told the others about how she behaved and although they were sympathetic and have continued moaning about her, she is still very much included in the group of friends.
We have a day out planned in a couple of weeks and this woman has been invited and tbh I know she will just be a total and utter cunt to me on the day out. And it's just dawned on me really that these friends, despite knowing what she is like, are not loyal to me in any way and are happy for her to just be vile to me.
AIBU to ditch the lot of them?
