A Way to Divorce Proof Your Marriage
"The object of love is not getting something you want, but doing something for the well-being of the one you love." Statements like this and many others are the treasures that fill this book. This book is a must read for anyone who is married or even considering it. It is full of real life accounts from people who had problems in their marriage, but eventually overcame them. These stories give not only ideas on what to do, but inspiration and desire to build a strong marriage. The 5 Love Languages are something Gary Chapman came up with after years of marriage counseling. He didn't come up with these out of thin air, he had so many experiences with relationships and discovered common love patterns among spouses. He concludes that there are 5 different languages of love that people speak. A love language is the way a person feels love from another. That could be through acts of service, or physical touch. Discovering the way your spouse feels love will save a relationship. I thought to myself, "Ok, the 5 love languages are listed on the back cover; what's the point of reading it now?" But after reading in depth about each love language my eyes have been opened on exactly what I must do to accommodate my wife's love language. The book gives so many examples; at least one of them is sure to be your case. If you didn't realize what you were doing wrong, the examples will spark that within you. I took notes and underlined many passages. At the end of each chapter he asks an open ended question to make you think about how you can apply what was discussed. This book is the service manual for any marriage. Study and apply what you read and I can assure you a full "love tank" leading to a better marriage.

Life changing advice that is simple to apply
When discussing building relationship skills with a therapist several years ago (and it is a skill, make no mistake), she recommended this book as providing a useful framework for thinking about loving relationships of all kinds — romantic, familial, even friends. Several years later, I can honestly say it has permanently changed the way I think about these relationships.
The premise, as you probably know, is that people have one of five native love languages — words, gifts, touch, acts of service, or quality time. It's a remarkably robust idea. It's so simple and clear that I instantly recognized the love languages in my current relationships, and even achieved a much greater understanding of some past conflicts by thinking of them in this new context.
For example, I realized while reading that my mother is 100% on the "acts of service" side. While she almost never gets sentimental, she shows love by doing all she can to help people out in any way possible — even ways that seem completely trivial. And I realized how much more hurtful it can be if I take these acts for granted, since these are her little expressions of love. It explained a lot.
I also realized that my partner uses "words of affirmation," which had been a source of minor conflict for us, as that's probably my least used love language. It turns out that he was a little hurt whenever I'd hang up the phone without saying "I love you." I've now taught myself to say it every time, and he's noticeably happier about it — or as Chapman would say, his tank is fuller.
After I read this book and held onto it for a while, I gave it to my sister. She read it, and we had a great discussion about the relationships in our lives. Chapman has really hit on something perfect with this little book — a simple theory that's easy to remember, remarkably accurate, and most importantly, instantly practical.

Perfect for special occasions or to brighten up any gift!
Color: Pink
This is a lovely, easy-to-use work with the satin ribbon; it's quite pretty. I wish the roll were a bit bigger since it's very small, but overall, it's a great product.

Coolest label maker I’ve ever come across
Color: Beige
Seriously this is such a fun way to wrap presents! It comes with ink and small labels. Must buy ribbon separately. But I love this and will definitely use it for years to come! It works via Bluetooth with an app on your phone. You can customize to whatever you want!
