I agree cards is a great idea.
A long distance friend and I were going through a divorce at the same time. Her divorce is still dragging on.
(and she disconnected her internet)
I am not much of a phone person,
so we have been sending each-other cards with supportive notes sometimes including little stuff like an angel pin,
book mark or pics of the dogs.

catnapper, believe me she will appreciate you being their
in what ever way you can. When she is ready she
will let you know. She might be ignoring your e-mails but
I bet she is reading them.
((hugs))
