Another child of divorce here, chipping in my $0.02: Yes, we are scarred from it, but all that means is that you have to check out the person and make sure that s/he has adequately recovered. If they came out ok, then there’s no reason to write them off. A few have said it already, but it bears repeating: many of us children of divorce are actually more motivated than a lot of other people to work on our marriages and avoid the mistakes of our parents, because we know first-hand the consequences of failure.
I also hate the argument that we didn’t have “good marriage models” to learn from growing up. Aside from the fact that there is plenty to learn from the bad- as in, what NOT to do- the assertion that we don’t know what good marriages look like is often patently false, especially if one or both of the parents remarried and did well. Both my parents are in successful second marriages (my mom remarried when I was 11, my dad when I was 15), and yes, I did pick up plenty of good habits from that.
One last thing- divorce is not the only childhood trauma that ought to be scrutinized in the context of a shidduch. Do people treat someone who lost a parent at a young age with the same caution? Well, they ought to. My husband lost a parent not long after his bar mitzvah, and believe me, he is plenty messed up from it. I don’t regret marrying him, b’h we are very happy together, but I can’t pretend that there weren’t problems- which all turned out to be directly related to his loss. I was put through the wringer because my parents were divorced, but nobody thought twice about whether or not the poor, nebach yosom was marriage material. Really, anyone who went through ANY significant childhood trauma needs to be looked at carefully, they may not be sufficiently healed to be ready for marriage.
