1. The Relationship Cure by John M. Gottman

The Relationship Cure

The Relationship Cure: A 5 Step Guide to Strengthening Your Marriage, Family, and Friendships focuses on the importance of emotional connection. Gottman discusses “emotional bids,” which are the ways that we ask for attention, as well as the best ways to respond to those bids.

For instance, one partner might say to the other “I had a really bad day; can we cuddle on the couch and watch movies tonight?” By expressly asking for what you want in a positive way, you can increase your chances of getting the affection and attention you want.

“The basic idea has to told with the way people, in mundane moments in everyday life, make attempts at emotional communication, and how others around them respond, or fail to respond to these attempts.”

2. The Five Love Languages by Gary Chapman

5 love languages

Chapman wrote several books about love languages, starting with The 5 Love Languages: The Secret to Love That Lasts. Other books in the series focus on subjects like how men can express their love languages better, how to communicate lovingly with teenagers, and how to keep love alive when a partner has dementia.

“With all the help available from media experts, why is it that so few couples seem to have found the secret to keeping love alive after the wedding?”

“Because the desire and drive for intimacy are at the very heart of marriage, the individuals involved become troubled about their relationship when such intimacy is not attained.”
