Very Married by Katherine Willis Pershey
One of the best ways to learn more about your partner is to use "personality tests" to help clarify the most effective ways to communicate. By understanding more about how a person works, a person can enhance how to show affection and respond to the other person in ways that enrich the relationship. (If you are having serious relationship difficulties, we encourage you to seek out professional help and pastoral support.)
"When couples read The 5 Love Languages, they discover why they lost the romantic feelings of courtship and how emotional love can be rekindled in their relationship. Once they begin speaking each other’s primary love language, they are surprised to see how quickly their emotions turn positive."
