The Five Love Languages: How to Express Heartfelt Commitment to Your Mate

The book is a quick read. It is written in a straight forward kind of way and makes sense on an intellectual, as well as an emotional level.
I truly liked the fact that he is pointing out the differences between true love and being in love; and does so much better than any other book I have ever read on similar topics.
I found the assessment of the love types very accurate. It is, however, not that easy to follow this advice, as most people lack the honesty, maturity and will power to keep up the work.
I also found that the advice may be easier to follow if one is Christian and a church going person. For those who are not it is probably going to be harder to implement or even understand at times. Example: Consistently fill the "love tank" of a spouse who is cruel, cynical and mean, in hopes that this will permanently alter his behavior eventually.
I will have to say, as a Non-Christian, it is very difficult to apply the "keep-holding-the-other-cheek" philosophy.
Still, I loved the book and I am actually making the necessary changes suggested.

I simply love this book! This book will strengthen any relationship if you adopt its principles.

This is a great book, it's a quick read broken into short stories.
The examples given are make you open your eyes and see things from a different perspective.
For guys trying to read a relationship book, this makes it simple and gives you a clear guide on what you should and should not do; I believe that this style works, it might seem overly simple with a "Love Fuel Tank" but it does work.

Highly Recommended for all couples young and old. Learn what you both need in your relationship and how to meet each other's needs. This book can help make a good marriage sweeter or turn around a marital relationship from just being hostile "roomies" to an enjoyable marriage union.

Gary Chapman provides a realistic assessment of marriage and common marriage complaints/problems. His suggested solutions are practical and easily adaptable. I highly recommend this book to people who are contemplating marriage, people who are happily married, and those who are not.
