So we invited a friend and their husband and kids to our toddler's birthday. I don't want her there anymore. The kids have probably interacted once a year and the husbands the same. The friendship is between the mothers and my friend proved to be very toxic a week ago. She crossed a tonne of boundaries judging me, my husband etc and tried to draw comparisons with her to make herself feel better. It was just a very messy conversation filled with put downs and boundary crossings. She was also trying to push some misogynistic family values whilst at it. Ive always been weary of inviting her to events because she is volatile with any community she is part of e.g. her kids school, her in-laws, her other friends and her own siblings etc. She is estranged from these groups and I offer a ear and advice but then she kind of showed me what it's like being on the receiving end of her behaviour. She has always wondered why people suddenly cut all contact with her. I feel awful about uninviting someone with a kid because the kid is on the receiving end of that but I really need to keep this friend away. In other friendships she has that has reached this point, she has tried to meddle with their relationships through others so I dont want to open the door for that by allowing her around our circle. How do I uninvite someone politely. her kids can still come if she wants but i cant see parents wanting that outcome
