18-12 for No surprises me,greatly !
50% + of marriages easily end in divorce.
Let me re-phrase, yes=
You have ever divorced, or your SO ever has, so Yes even if you are not married now, but date a previously divorced person.
Must be a lot of 20-25 year old types answering, seems the likely answer.
A whole lot of peeps I know that are 50ish, have failed marriages, so the probability of you or the SO ever having been divorced should be high, unless respondants are younger.
