Now that you are aware that your W sensed your attitude, you can plan ahead the next time you see her.
Know that you are going to be feeling angry and sad in the near future. Have a plan in place for when you see W. You need to project that you are ok, that you are strong, and that you can and will live a happy and successful life.
You need her to doubt herself. She won't doubt herself if she sees you stewing or moping. But, if she sees you as a strong, confident man, she might start thinking "hmmm... am I doing the right thing here?".
Bottom line... you know you can expect to feel crappy while you go through this. Have a plan.
