Well, as I said, I did wonder if something else was going on, that you didn't know about. It sounds as if this could be the case, and that she is sticking close to just friends & family because of it.
However ...
It is always possible that she has been told something, about you, that has rocked her trust in you.
Maybe someone invented something, or she misinterpreted something, or she discovered sonmething that she didn't like.
Or maybe it is something that has nothing at all to do with you.
Give her some time to sort out whatever has happened in her life ~ and hope that she will contact you.
And writing a letter is not the same as sending an e-mail.
A letter is tangible. It has your handwriting on it. It can be kept under the pillow and re-read whenever one chooses.
I wish that I could be more helpful.
I'm confused by it, too.
