Divorce is becoming very common in the jw community. At least 6 couples in my last congregation, (including my ex-and myself), were either divorced or separated within the last 3 years.
I would certainly say that the WTS contributes to this, at least indirectly. If we consider the aspects involved, it is easy to see why. First, dating is off limits, unless marriage is being considered. So what happens, young, horny people get married too young. I don't need to tell any adult what kind of mess that can potentially make. Bad start. Then, there is all of the "Theocratic" nonsense that pressured onto the marriage. This is no way helps. Especially, if one of the marriage mates, (like my ex), has some deluded understanding of what being a truly "spritual" person is. In her case, it was all about image. Very fake, but very common in jw land. An honest person cannot put with this for long, without needing to be medicated.
Finally, when things get to the breaking point, the only "scriptual" way out is some form of adultery, (this makes absolutely NO sense). So let's see, let's have a one night stand, just so we can get out this mess! Any thinking person can see what is WRONG with this. Much better to just leave the abusive situation. I usually find most people, (at least one of the marriage mates), will leave the org. when it comes to this, simply becasue it's one of those things that makes one clearly see what is wrong with the "biblical" counsel, and the legalism of upholding it.
