The more you attempt to get the info out of her, the more determined she will be not to be cooperative and give it to you. Drop the questions about the mediator for now and wait. When she sees you aren't taking the bait for an argument or appearing to beg for info, she will then open up.
Just leave it alone for now...trust me....her tune will change when she sees that you aren't bothered about the info.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
