You were right, Ann! I had the same thought and I got my daughter to open up a tiny bit by sharing a little of my own anxiety over the unknownness. And she surprised me by saying even though she wants to have a future where things are ok with her dad and 50/50, she wants things to stay like this for now (with me, doing supervised visits).
That was both good (I am glad I know what she wants and I can do my best to get her that), but bad (she has previously always wanted to be at both homes, so obviously something isn't right).
