Yes - I can't really even bring myself to type out how bad she was. It took me a long time to realise the full extent of it. She is a pathological liar. i sussed a fair bit of the behaviour early on but it took me far too many years to realise the full extent.
Her lies were both outrageous and scary - the small embellishments you could take with a pinch of salt, but when she started lying about other people and it affecting their lives etc it was scary to see how twisted she was.
She has no friends left, her siblings have no contact with her, she has gone through multiple husbands and boyfriends before they cotton on.
I don't want to write war and peace but she displayed stalkerish behaviour (deleting numbers from our phones etc) and stole off people - she was very clever and difficult to pin down, if you did call her out about her behaviour she would get aggressive and defensive.
She went too far one night and I left in the morning and never spoke to her again. I did see her at a party about 5 years ago and she approached me to "make up" but I just blanked her and have heard recently she has moved far away.
I found the whole process quite traumatic - I was friends with her for about 10 years and it took a long time for things she had done to me come to light or for me to make sense of strange and odd things that had happened.
