I cannot think of anything else that would not appear to be pursuing.
If you will maintain the attitude you have right now, then going dark may be all that you have left. The holidays can be rough on people who are going through M problems.
My suggestion is to continue doing what you are doing now. Wait and see if she attempts to make any contact first. One day at a time.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
