Is there ANY REASON to think that in two weeks things will have gotten any better?
What do you have on the go that would suggest this is the case? From my reading you are not planning anything to be better, just hoping it will magically imporove.
Right now your wife isn't afraid of your position because there's no consequences... nothing different happens when she contacts him, so she's going to do it.
How do you plan on disciplining your children? Just wait and hope that they behave better in two weeks?
