For her to say she "doesn't know" means just that. She does NOT know right now one way or another.
My WAW on exit #2 assured me she could NEVER, EVER in a million years be intimate again-EVER, and therefor could never be a wife. After 10 months and calling off the D the day of the hearing we got back together, and guess what. She found out she was utterly and completely wrong, (to her great surprise and our great delight).
For some humor (which almost always helps) remember in dumb and dumber when Jim Carrey asks the blonde bombshell if there is a chance he and her will ever get together, and she says, "like one in a million" and he is like-yippee you are saying there is a chance. It's how you look at it!
