I've been married for 3yrs,no kids yet. We've had our share of problems but we're generally happy. Loved the book but I think he should have focused more on the positive, so 50% of marriages end in affairs, but what about the other half that doesn't...how about a book on that???

Still here?

Are you asking about the marriages that end for other reasons? Or for books on marriages that don't end?

I'm sure there's literature about the former, but I don't think there's a big market for advice-type books marketed to those in successful marriages. There's more feel-good stuff, think of things that the folks at Chicken Soup would put out.
