i've tried several times, both by phone and by email, all for naught.

She still is advertising (see link).

I did see her once before Thanksgiving and we said that we would keep in touch.

She told me that she was buying a house in QC and that she would take a couple of weeks off, but that should have been done by now.

I sent her a "Had a wonderful time" e-mail; never heard back.
I sent her a "Are You Okay" e-mail; never heard back.
I sent her a "Please Call" e-mail; never heard back.

I figured she didn't want to see me anymore, but based on this thread and above reply, I now wonder if something happened.

GlenAZ or any of ladies, do you know what happened to her.
