I think I may have ghosted an ex-friend, but I'm not really sure.
She was never a BFF, but we were good mates for over 20 years. She's always been someone who likes to compartmentalise her life, and she had lots of other close friends, most of whom rarely met each other. Our friendship had always been rather on her terms because of this.
As the years went on, she developed a bit of a drink problem. We still saw each other fairly regularly, but she became more and more unreliable and would often cancel at the last minute with barely credible excuses, some of which turned out to be lies (basically, she'd got a better offer!).
By this time, she'd moved 50 miles to a town a few miles from me, and basically expected me to be her unpaid chauffeur on boozy nights out. Among the last straws were me booking a holiday cottage for us both, and her coming down 3 days late, claiming pressure of work. When pissed on the night she finally arrived, she disclosed that she was now shagging her lodger and she'd opted to spend the weekend with him rather than come away with me, as planned. She also invited her son to join us for "an evening" but he ended up staying with us for 3 of the 4 nights left, and she expected me to do a 40 mile detour to take him back to his digs "on the way home". On another occasion, we went out for lunch in a pub frequented by some social and professional contacts of mine, when she got appallingly drunk, loud and foul-mouthed and I was profoundly embarrassed.
My now DP was also a good friend of us both. When we got together, she sent him several really abusive texts, calling me a "fucking bitch" and saying, among other things, that I'd only been friends with her so I could get close to him (which was funny in a way, because we'd both thought she was trying to get us together).
She still acted like we were friends, and he only showed me the texts when she'd broken yet another arrangement to meet, and I was very upset.
We had no contact for several months, until our paths crossed by chance and she just acted like nothing had happened. I was so gobsmacked I couldn't say anything, and she'd arrived (drunk again) just as we were leaving.
I've never explained why I want nothing more to do with her, but reading this thread makes me wonder if I ought to, should the occasion ever present itself. Mind you, she has such a selective memory that she'd probably refuse to believe me and/or it would just turn into a huge row.
