This could be the main reason I have seen so many divorces of JWs married to JWs over the past 20+ years that I've been in the WT religion, and a very low percentage of JWs that are married to a non JWs who divorce over this time. Now here comes the WT brain washing part of this statement. Try mentioning the fact that I have witnessed many JWs get divorced over these 20+ years I've been in (trapped) and you will most likely get shot down in flames for speaking negatively about the beloved WT religion, or has an Elder once tried telling me, "in the world they have way more divorces than JWs".
There was a part in this weeks meetings where it was brought out that if worldly people would only start studying with JWs, they would find that there marriages would become a lot more happier.
