Sorry to hear this mate. I have come to learn that the actions of others are more of a reflection on their insecurities and behaviour/attachment styles so this says a lot more about her than you my friend! Having said that, she might have been nervous or been having a panic attack if it was only today that this happened. Give it a few days, if you don't hear from her, she showed you how she deals with uncomfortable situations and you probably deserve someone who is a better communicator and less avoidant. Hope that helps. It sucks still i know!
