Mat, I don't think you're under any obligation to tell her to whom you're turning for advice and support. I would stay mysterious, and say something vague like "At times like these, you really learn who your friends are," or "I'm doing what I need to do in order to get some advice and support from a few close people I trust," and leave it at that.
She has walked away from you. You need to let her put on her BGPs.
