She believes she has moved on and you have not. What do you think it means? The way I see it, for your wife the marriage is over. She has not doubts at this point. So you have to start changing her mind. Give her doubts, make her wonder if you really are the one, make her wonder if she is doing the wrong thing for the kids, make her wonder and make her doubt she's doing the right thing and keep at it. It all starts with more time together....family night.
