Yes I have but have also had it done to me.
My own cousin ghosted me when we were 16. I saw her one day walking towards me and rather than speak to me she crossed the road to avoid me. Saw her again, tried to say hello she turned and walked away. Ten years later after I was married and had kids, at a family get together she tried to approach me, childish I know, but wasn’t interested so I didn’t acknowledge her. Still don’t speak, both in our 40s now.
Old neighbour just stopped speaking to me one day, then many many months down the line started speaking like nothing had happened.
I don’t know if I ghosted her or she ghosted me but like others have also mentioned, I realised I was doing all the running and one day thought fuck it, won’t contact to see how long it takes for her to contact me. I’m still waiting....14 years later!!!😀
Most recent person (3 years) is the most narcissistic person I know. I could no longer deal with the moods, attention seeking, lying, negativity, all about me attitude, playing the victim etc. She was having a really bad effect on my mental health. I felt she was bleeding me dry emotionally. I had been limiting contact for a couple of years already but the final straw was the inibilty to put her child first over herself and many relationships, so I kind of just stopped contact, I didn’t have anything else to give nor did I have any fight left in me to confront the issues with her and would just lead to the deny, lie, cry, response I always got so no point.
Months down the line she turned nasty on 3 of the people closest to me and caused a huge amount of hurt. So I know I made the right decision
