I think RJ has some really good points and it seems you might have already implemented some of them before with good success.
Definitely stop the crazymaking, there is nothing you can do about any of it. Just trust that she is making the best decisions she can make, and care for her unconditionally. Take care of yourself during this time and do your best at detachment. You'll be a happier person and your PMA will show. Isn't that how you'll eventually draw her back to you anyway?
