I would not do the work of ending the relationship, I would let her handle that. You are thinking way too much. First off, quiut texting her, it is time to drop the rope. It is never too late to DB, because it is for you. What do you do for fun? Time to start living your own life, she sure as hell has started and it is driving you crazy. Time to drive her crazy, be mysterious, make her think you are having the time of your life and then actually do it!
So, my advice, do not do anything that will expediate the divorce, but act as if the relationship between you two is over, and that you are moving on.
