If you meant what you said to her. (and I sure hope you did) then if she doesn't respond........
YOU take action. You don't need her permission to speed things up. Get things going from your end. You be the one to take the bull by the horns. You will get much more for yourself when they initially want out than you will by waiting and giving them time to think. They will usually be much more compromising when they want out.
If you don't mean what you said, then you put yourself in another dilemma and more drama. When dealing with women, you need to say what you mean and mean what you say. Always be nice, but it is ok to be firm and decisive.
If she responds slowly you need to SHOW her you meant what you said. Why would you wait for her to do everything? That is weak.
