The first new times she opens up it may just be sobbing and no intelligible content. Eventually if you are supportive through that it will get deeper and she will begin to talk.
You just have to keep up what you are doing...making damn sure she gets to see what you're doing so it wears on her conscience.
When you get calls like that it could be one of serveral things:
1. She's having a meltdown from all the stress. A good sign. 2. She had a fight with OM. A good sign. 3. Her conscience is beating her up, and your efforts are tearing down the wall of anger she built up. It's a good sign.
If she was at her lawyers and sobbing I might go with something else, but on a vacation spot those three above are most likely.
