Good discussion book to eliminate conflict between couples
Format: Kindle
Use this book as a checklist of things you should discuss with your partner - especially if you're considering or are in a long-term relationship. It explains each topic, why it's a likely source of conflict, how to prevent the conflicts, and includes questions for discussion between partners. Understanding and discussing these topics may not feel romantic and fun, and some of the conversations may be challenging for couples who aren't accustomed to such discussions. Do it anyway though because it will eliminate future conflicts before the conflicts even begin and make your relationship run smoother, last longer, and be a source of relaxation and contentment for you both. I'm speaking from experience here.
If you are new to the study of this topic, this book will be extremely valuable for you. If you've already studied interpersonal relationships, preemptive conflict resolution, and collaborative negotiation tactics, it's still a great checklist of topics to discuss with your partner. I'm on this end of the spectrum, hence 4 of 5 stars because I'm familiar with the author's other work and this book didn't contain much new content. As a compact, all-in-one, relationship discussion guide though, it's great and worth reading and having on hand for future reference for new relationships or for when new conflicts crop up.

Great for Everyone!
Format: Paperback
This book is very useful to prepare people for marriage and I would recommend it for teens (even if they're not in a relationship), engaged couples, and even those already married since this provides realistic information about love and that not everything in a relationship is easy. It also helps people understand and attempt to loosely preset chores around the house and understand what to do with the extra money earned that isn't needed for bills. While I was already aware and have read about the 5 love languages, that is only briefly covered in one chapter while the rest provides other information so if you already read the 5 Love Languages book understand that there is a lot more involved in this book than that concept.
The concept that I want to highlight in this book that I haven't read about before was the 5 Different Ways to Apologize. Increasingly, I think people need to be aware that what we consider to be a 'sincere apology' isn't necessarily the same as everyone else's though there are 5 of them that are fairly common. I was surprised when I found what I thought to be a sincere apology was listed word-for-word! This concept alone can be applied to anyone you socialize with and I especially recommend this piece if you are having apology problems between your friend, significant other, coworkers, and/or boss.
Teens and those single will be able to learn a lot from this book, especially to realize that people, on average, are no longer "falling in love" within two years of the relationship and I think this would help them understand that relationships take a lot of work even when it's not convenient for you. Giving them an understanding of how to be flexible when apologizing and to know that people feel loved according to different love languages will make them more aware of how to improve their friendships and relationships in the future. Finally, there is reinforcement in being willing to do chores even if they're not popular and generally establishing healthy spending habits.
I personally found this book to be thrilling and Gary Chapman successfully backs up some of his findings with Psychological research and definitions. I loved it so much that I read it in one sitting and now I'm getting my teen friends and budding couples into reading it. Awesome book; give it a try if you haven't already! (:

I love this!
Format: Paperback
This is a different type of marriage book. It’s very practical and addresses topics will affect you marriage that you can discuss beforehand. Many of these things get figured out along the way by way of arguments and disagreements or worse, just acquiescing without agreeing. (10 years later this is the reason you’re getting divorced and you haven’t ever talked about it. The other person has no idea & you never trusted them enough to tell them your feelings.). These topics range from who is going to clean the toilet to handling money and marrying into another family. It’s good practical thought and food for discussion. As the first chapter says “Being in love is not is not an adequate foundation for a successful marriage.”

Thank You for this Incredible Book!
Format: Kindle
I am 19 and I am "unofficially" engaged. I know that he and I will most certainly without a doubt be getting married. We have known each other since we were 5 and 6 years old and have built a friendship with God at the center. We are trying our hardest to do things that right way considering we have both come from very (for lack of a better word) dysfunctional house holds. Both of my parents being on their third marriages each and his finally coming back to The Lord after many years of living in the world, haven't always been the best examples for us to learn from. We know exactly how we don't want to lead a marriage but we were not sure exactly how go about leading a proper or Godly marriage. This book, which I accidentally stumbled upon a few weeks ago, has been a serious eye opener and a total reality check. Though I will admit we were in the "tingles" stage, as Dr. Gary Chapman puts it, we have always tried to stay realistic. "Things I Wish I'd Known Before We Got Married" has truly taught us a lot of valuable lessons and I know we will keep the things we have learned from this book close at hand in the coming years.
We thoroughly enjoyed reading this book, but what really made it interesting and kept us flipping the pages were the little anecdotes that were shared about other couples. Listening or reading their experiences really helped us relate to the situations that were being explained. We also liked the "Talking it Over" segments at the end of each chapter. Those we extremely useful when it came to understanding all the information that was just handed to us in the previous reading.
I can not stop telling people about this book. I already have my sister and her husband reading it and it has greatly improved their relationship now after almost 4 months of marriage. I have also recommended it to each of my parents and my fiancé's parents as well because I know they could greatly benefit from it as I did.
Thank You!
