Bit of background:
Me and a close school friend moved to a new area together (purely by coincidence) and decided it would be nice if we could both try and make new friends together as both of us were a long way from our families and didn't know anyone else.
We became friends with a group of women through a club we both went to and everything was fine for a few months, until July last year where she inexplicably turned on me, spread nasty, vicious lies about me through the group, who subsequently turned their backs on me and left me with nobody. She also harassed my family, claiming I owed her money (which I didn't), and various other pointless lies which caused me undue stress.
I was then diagnosed with depression, I lost my job and got into debt, partially due to the stress this had caused. She used to ring me constantly, leave me voicemails and laugh at me for having "no friends".
Fast forward to two weeks ago when I saw her on a night out with her sister who had come to visit, she was visibly upset and told me that the former group of friends had now completely dropped her, she was also sacked for gross misconduct and is struggling to find work. I was sat with about 8 of my new friends, who are all kind, lovely and have welcomed me into their group. I also have a much higher paid new job and am depression free!
SO AIBU to feel like a smug bitch that karma has bitten her on the arse?
And WIBU to tell her to piss off when she asked about coming to socialise with my new group?
