This book is one of the most helpful books ever concerning relationships! It could be the only one you would need for marriage or parenting because if you can understand your loved ones primary love language, find and give acceptance for one anothers love language, and begin relating and showing love based on their love language, then Love Really Does Cover All! They and we can feel loved in spite of our shortcomings, mistakes, and whatever life has. All of the advice and techniques in the world on love will not work well if the other person does not feel loved in the language that is most meaningful to them. This book has helped me with my 3 kids more than any other. Also the one on the Five Love Languages of Teenagers was immensely helpful for the same reasons.
