I've recently come to the conclusion/realisation that a friend of several years is not a friend after all and is backstabbing me at every opportunity. By backstabbing me I mean bitching about me behind my back to mutual friends and trying to turn others against me, whilst still being nice and friendly to my face!
Over the years that I have known her several mutual friends (whom I have introduced her too) have all gone cold towards me. Another mutual friend has told me recently that my 'friend' bitches about me a lot, focuses on my flaws and points them out to others all the time and tries to encourage others not to speak to me.
Unfortunately I have to see said friend every day on the school run as our DS's are friends at school (which is how I met her originally) and are in the same class. It is a small village school so there is no avoiding her at all!
I don't particularly want to confront her as I don't think that people that behave in the way she behaves take any notice of being confronted and just use it to their advantage ie to make out that the person confronting them is a total loon.
How would you deal with her?
