Perfect! It would have been better if she had broken up with him.....but this is the next best thing! She may feel scorned and act out, IDK.
My suggestion is to keep acting as if you are normal (especially during holiday season), and don't give her any "reminders" of how you feel or what you want.
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!
