She certainly left no room for ambiguity! It would have been more cruel of her to have gone ahead with the date. Personally, I would prefer the sprint to a stammering explanation of how she doesn't want to hurt my feelings, but isn't interested in me in that way, all the while trying to pretend that she cares about my feelings and wants a farcical friendship. You should probably thank her next time you see her.
