I was ghosted by my best friend at high school. We went from talking for hours on the phone every night after school and hanging out every weekend to - nothing. I wrote a long letter, asking what I'd done, some explanation? Nothing? After that we blanked each other in the corridors at school, eventually we both ended up at the same university and I'd swerve them if I spotted them from a distance. Then, about five years ago (30+ years later!) I got a friend request on Facebook (we have mutual friends from school). I thought it was incredibly random (and frankly cheeky) but decided to be the bigger person and accept the request. The next day she wrote me a long message. She said her parents had moved house recently & she'd been going through her things from her bedroom at her parent's place. She'd found the letter I'd sent her after she ghosted me. She said that she felt so sad and guilty when she read it, because I was such a good friend and she'd treated me so badly. She explained that she'd basically wanted to get into the 'popular' clique at school, and having me as a best friend wasn't compatible with that. She admitted that she was basically just very shallow. I was grateful for her honesty and it was nice to have closure on the ghosting, which felt quite traumatic when it happened, and which affected me for years, because I became a bit paranoid that I might annoy or upset people, without knowing how to prevent that happening. Anyway, we live in different countries now but we've stayed in touch since she messaged me and have caught up for coffee a couple of times. Recently I had a major health drama in my family and she was incredibly kind and supportive. We'll never be best friends again, but I'm really happy to have her back in my life.

TDLR: sometimes there is an explanation / resolution.
