would presume somebody who gets divorced over trivial reasons is far riskier to marry than someone who divorces over a reason that’s serious”
I don’t necessarily disagree with you. it may be, however, ther easons are “trivial” because the couple is still too immature to get married, a phenomenon which we see more and more, as couples who are not independent are getting married too young, and really are only playing at marriage. They are for whatever reason not ready for the real challenges of married life. And my generation has done that to many of them, by fostering a co-dependency on the parents. Serious reasons do not often manifest themselves until the couple has really gotten to know each other. That often does not happen until after marriage nowadays.
