Why are some marriages more successful, more satisfying, and more enduring than others? The answer to this question is perhaps the most widely studied and best-kwn part of our marriage and family-therapy literature, although arguably, it is the least understood and certainly the least followed in terms of avoiding the pitfalls that lead to unsuccessful marriages. What this book proposes as an answer to this question is the nearest thing we have to a manifesto for marriage and family living. It provides us with a clear description of what married life should be like. No words or ideas sum up the intention of this manifesto better or indicate more clearly its challenge to contemporary marriages than the words making marriage user-friendly.
