Man, I don't know. I have no advice to give you. But, I can totally understand your frustration. She is all over the place with playing with your emotions. You have some good control. I would be flipping out.
The one thing I will advice you to do though (if she does come back after 12), is to act as if. Don't even let it bother you. Be the bigger person. The silent treatment will not prove anything to anyone. It may make you fell like you have control, but quite the opposite. It will just prove to her that you are an ass (since she thinks you are blind to her and OM, because she is to sneeky for you). And it will also drive her farther into the arms of OM.
