I agree with zahavasdad. In my parents generation, there were few divorces. One, was due to the husband straying, and another, abuse.. and the abuse couple were Catholic, which was unheard of. Now, if the couple is miserable, they can divorce because the wife is able to work.
I have seen several former students divorce. The ones that divorced were married before she had an post seminary education and was literally pushed into marriage by the parents. The girls that are in a successful happy marriage have degrees and careers, maybe that is why it works.. more of an equal footing.
