Joseph:
1. Americans in both EY and Israel
Approximately 35+
I am basing this not only on my own friends and acquaintances but on their friends and acquaintances and people whom I hear about.
I have been in many places and have met many types of people, and the Frum world is not that big, and the population of American Frum single girls who are 35+ is not so big, and I tend to hear about a lot of the single Frum girls of 35+ who get engaged (whether or not I know them), so I am fairly confident that while not a scientific study, it does seem that a significant percentage of older single girls who get married end up marrying guys who were married before.
It is also based to some extent on things that I have been told by shadchanim that would lead to this conclusion (albeit indirectly)
2. I wouldn’t have thought so either until recently. But the older I get, the more I find that the divorced guys who are suggested to me have often been divorced more than once. It’s probably not most though, but there are a lot more than I would have thought. As you get into higher age ranges, I think the percentage rises greatly.
3. I’m pretty sure that I have read that, but I can’t remember the source. I think that I heard of it from more than one source.
4. I was expecting you to say that. Sorry, but I don’t think that any of your sources are proofs to that effect.
Also, please reread my last two sentences in my above post. I was not getting into a debate about whether or not most divorces could theoretically have been prevented.
The point is that regardless of whether or not theoretically it could have been prevented, that doesn’t make the people selfish and lazy and it doesn’t mean that they didn’t have good reasons for the divorce.
