I need to extricate myself from a friend, I've only known her a few years, most of our communication is on social media where she's fine but when we get together she's rude, interupts people all the time. She's clever and had a really good career before having children which she never lets anyone forget. Whatever anyone talks about, has done, enjoys or even mentions she 'tops' it. Shes been there, done that and bought the diamanté encrusted r shirt.
I plan to avoid all future real life interaction and will have to tell our mutual friend why. Any ideas how I can extricate myself from her or call her on her behaviour without creating mayhem?
