She is testing the waters to see if she can get a response out of you. WAS want their freedom to do what they want, but also still want to know you are hanging on pining after them too. Your best bet is to treat her politely but maintain your distance. Don't initate and don't try to keep conversations or texts going. Respond politely only to what is asked and let it drop. Don't go out of your way to be nice. She expects you to be upset and to chase after her. If you don't play into her script, it's going to make her wonder why you're not acting as she expects, and makes you look a lot more interesting and appealing to her too. People want what they can't have.
