Jeff, Do not ask her what waffling means to her. Just let it go. Time is on your side and trust me, if you sit patiently and observe, tidbits of what is going on in the mind of your wife will be exposed, piece by piece. Just sit back and listen. That's all you have to do for now. No questions at this time.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
