Of some interest, I heard Fr. Rutler [sp?] EWTN say that with couples that don’t use contraceptives there is less than 1% divorce rate but for couples that do, it’s 60%.
Regarding cost of wedding. My pastor said the more that is spent the more likely a divorce. No stats.
I've always thought that the length of a marriage is inversely proportional to the number of attendants at the wedding. ;o)
