Heres my take FWIW.

MWD and some other marriage guru's all seem to say that if you are having marriage troubles that things will change.
That 5 years later (and I think that is arbitrary) you can be in a fantastic marriage.

And I have friends that have verified that their wives went off the deep end for around 5 years but now they are happily married.
So do you really think that UR has to shake things up when this has only been going on for a year?

As far as him telling her in words.
Hmm I would tell his wife to believe nothing he says and half of what he does.
So I dont think you can make an empty threat and it will have any weight.

I also think that her crisis so far has been very mild.
The downside to that is I think it will take much longer.
Higher energy sometimes burns the fire quicker.
Just my .02
