I think it's only natural for you to feel a bit sad today.
You've been great through all the threads but it's still a friendship you valued and it hurts to realise she didn't feel the same way about it. You wouldn't be human if you didn't feel hurt. You'd be some sort of dinosaur-gluestick hybrid in a veil.
At least now you can put it all behind you, you won't have any more appeals to help popping up in your in box and in time she might now calm down and realise what she's done and why you were perfectly justified to feel the way you do.
