Well to play devil's advocate here it is unwise to get into the middle of a marital dispute without knowing all the facts . These things can end up coming back and biting you . The point about ultimately being responsible for the outcome is valid .
However l am really not sure about automatically sending someone off to talk to Elders . How qualified are they in giving marital advice, especially knowing how they misinterpret Scripture.
I would have thought that if the situation between husband and wife was that bad then marriage counselling was appropriate. That's never going to happen though because a Witness would never talk to a " worldly " person about marriage, or anything else.
