For many years I misreported and said the divorce rate for second marriages was 60 percent and 73 percent for third marriages. My numbers were based on a census report but thankfully my friend, Shaunti Feldhahn, discovered in doing research for her book, The Good News About Marriage, that the data was misreported by an official. The mistake was reported around the world. We now know that we overestimated the blended family divorce rate by 10-30 percent. Hey, my mistake is good news for you.
