Happiness, is it even possible.

[fearless]

their W's may have convinced themselves that they (the marriages) are just fine. Thus, they are happy campers.

I don't think we know enough to assume definitively this about the wives. Maybe they aren't happy with the marriages either but they don't know how to change the marriage and have just decided to live with it. Or maybe they are happy "enough" with the marriage or maybe they get their happiness somewhere else - job, motherhood, etc.

And even if they "seem" happy, that doesn't mean that they ARE.
