How do you break off a best friend relationship?
They're nice to me but we have heated arguments bad especially vegan ones. I'm a vegan she's not and this is a huge deal because I'm cool with her eating meat in front of me but she has made comments on Facebook I can see them where she says "of course they're a vegan" and "I don't support vegans" and it gets us into an argument where we end up shouting at each other. I also organize vegan events and because she doesn't support veganism she doesn't come to any and it hurts me I feel like it's toxic to be best friends with her. It was a 9 year relationship and it was amazing but the last argument was when she finally did come to a vegan event she made a comment saying she still doesn't know how anyone could be a vegan and we fought in public argued in front of the other people there who were vegans.
We haven't spoke in two days because I told her to call an Uber and she left while I stayed. I can't be friends with her anymore she is against vegans and I'm vegan so it doesn't work. I've been a vegan for 3 years and vegetarian since birth.
How do I end this because I know she will call me and then we will argue again I just want her the hell away from me
