I'm sure she's intrigued by you doing so well. She may even be asking stuff in the hopes that you're still upset and that the door may be open for reconciliation if worse comes to worse. She could even be a little worried that you're moving on. I think you should give every impression that you've accepted the inevitable and are moving forward with your life. It's especially important that you be upbeat when (if) she does move out. Help her move and be happy about it. Be excited...there are some benefits to having a little space and freedom for you also. The more doubts you can put in her head the better.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
