You are doing great! I think it needs to be said that LRT can help a wayward to miss you, and start coming around, as in the squirrel analogy. But it will not rebuild a relationship. It is essential, especially when the wife left because her husband treated her badly, that he 180 his behavior and actively be nice and loving, as Denver is doing. I have seen some people have such a fear of pursuing the spouse, that they LRT all the way to the divorce. And then they wonder what happened.
You cannot build a marriage on GAL, and showing no interest. Somewhere, if the time is right, you have to reverse course and build a life together. Marriage is two people who do things together. Not ships that pass in the night.
