How say you .?
I look at the bigger picture. When you take a closer look at things, sometimes you find that some couples have a lot of issues and they become JW in an attempts to either fix them or escape from them.
When it comes to marriage, we just don't know what happens behind closed doors between the couple. Coming to any conclusion based solely in what outsiders see, or based only on the word of one of the parties without the others, I'm not sure it's going to get use the entire story.
That said, it's well known to many of us that the WT can't care less about the well being of their people. All the "advice" that they provide is for their benefit and to push their agenda. That includes what they expect people to do in their marriage, and they go as far as telling people what positions are acceptable when they are in the intimacy of their bedrooms.
When it comes to the health of a marriage, it's not a good thing to rely on what the WT says. When a marriage is in crisis, they certainly don't help, but I wouldn't hold anyone responsible without knowing the entire story.
