My friend has and I'm sad about it.
We were good friends, saw each other a lot, had a lot in common. I moved some miles away and I saw her twice in an eight month period (fine) but she and I emailed, texted one another reasonably regularly.
She went away in January, sent me some pictures and I replied saying it looked beautiful.
Have heard nothing since - texts and emails have been ignored (I know she's safe as she owns a small business and that's running well.)
Has anyone else just suddenly never heard from someone again?
