I think by ignoring her will probably draw her to you more - we have a habit of wanting what we cant have. However, is that what you want? It probably wont be enough to have her come all the way back and you know this is her 2nd time in your R with her when she has walked away and had an A. I dont think it is in your character to be rude - you should maintain the friendship, but maybe lesson some of the contact if it is still causing you hurt.
Hypothetically, if your W wanted to come back, what would you need from her to convince you this would never happen again? If she were to convince you like the first time, would you believe it would stick a second time?
