The Seven Priniciples for Making Marriage Work

Dr. John Gottman is one of the world's foremost experts on successful marriages. This book is the culmination of decades of research. It's about building friendship; enhancing love, warmth and mutual respect; and learning to handle conflict without damaging the relationship. At the moment, this is the self-help book I recommend the most to couples. If you were only going to purchase one book, I would suggest this one.

The Five Love Languages

In an engaging, often humorous style, using lots of examples, Dr. Chapman teaches couples how to recognize and speak each other's love language. This book clearly illustrates how being unaware of differences in the way that each spouse shows love and needs to be loved can be a root cause of much unhappiness in marriage and how to create connections and closeness by learning to speak each other's love language.
