Empirical stats I have seen indicates that the divorce rate is the same for the Jehovah's Witnesses as the rest of society. All the literature education has not made a whit of difference.

I'm not sure those statistics are accurate. What means did they use to gather that information? Do you even know? There's more involved than just “literature.” One thing I've noticed on these forums is people have a very superficial perception of Jehovah's Witnesses even though they claim they used to be one. Do you even know what the literature says?
In a nutshell...
Works for family and interpersonal relationships:
w07 7/15 p. 21 par. 2 Will You “Keep Walking by Spirit”?
As we “keep walking by spirit,” God’s active force will motivate us to obey Jehovah. We will display godly qualities in our ministry, in the congregation, at home, and elsewhere. The spirit’s fruitage will be evident in our dealings with our marriage mate, our children, our fellow believers, and others.
Does not work for family and interpersonal relationships:
g03 2/8 p. 13 Is There an Unforgivable Sin?
Some people who were once faithful Christians have purposely drawn away from God, perhaps because of bitterness, pride, or greed, and are now apostate fighters against God’s spirit. They willfully oppose what the spirit is clearly accomplishing. Have these individuals committed the unforgivable sin? Jehovah is the final Judge.—Romans 14:12.
Rather than judging others, we do well personally to guard against committing secret sins that can gradually harden our hearts. (Ephesians 4:30) And we take comfort in the fact that Jehovah will forgive us in a large way, even of serious sins that we have committed, if we are repentant.—Isaiah 1:18, 19.
Not that everyone who's unrepentant and spiritually deficient is dysfunctional, but they're generally the people that adversely effect family and friends in the organization as they make their departure. That's been my direct observation.
There are people in my family that are not apostate but they're not one of Jehovah's Witnesses. Most of my siblings and several of my cousins were raised in the organization and later left. I don't try and force my beliefs on them and vice-versa. We rarely even talk about religion.
