Volley -- want to ask her our but just a month ago she said she couldn't/wouldn't do that without MC -- this strikes me as a perfect scenario for a Spy. Do something covert. Surely there's something you two need to discuss, look over, consult on, etc.
Remember the way one used to get a "date" but not a "date date"? Um, I wonder if we might sit down over lunch, and.....?
So create these no-pressure dates-that-aren't-dates, and let her see that the two of you can be "out" "together" without being "together." Maybe that would take off the pressure of being "asked out."
