What about the rules in regards to the WW filing for divorce and maintaining her affair?

Is it too late to apply all of these rules or is that one of the of the times where it makes the most sense.

Not pursuing, saying I love you, asking out on dates seems like no brainers at this late in the stage.

When they have filed - is it too late to have these 37 rules still make an impact?
