Which is exactly what I said. It does not say that 20% of all marriages end in divorce, only that of those that do end in divorce, one in five CITE Facebook in court filings. It does not indicate that divorces are on the rise, by 25% (which it would be if all these marriages remained intact otherwise) or any that had it not been for Facebook the couples would now be celebrating their silver anniversary. I doubt that many marriages now end in divorce because of Facebook.
I think it's a good idea if married couples have access to each others email and other computer accounts, just to build trust and maybe help your conscience.
I didn’t say 20% of all marriages end in divorce, I was questioning whether 20% of all marriages THAT end in divorce do so because of affairs exposed on facebook. That hints at 20% or more of all divorce being because of adultery.
