I went in to make my younger one some dinner and W noticed that I probably looked a bit distraught and asked me "What?" I said, "Nothing. I don't have anything to say - maybe next week." She kept probing me for what I had to say, but I stuck to "Ask me next week." (I'm thinking after my D's birthday party.) She said, "If it's about my future, I need to know about it." But I just left the room.
Excellent -- let her twist.
It's not your job to make her feel good about her poor decisions, and deceit.
