This book is a self-help guide intended for older or middle-aged people who want to form a new couple, and for couples, not young people. It is a reminder of most of the factors or ingredients that make a relationship strong and lasting. Many times with the passage of time we forget to apply these ingredients in our relationship because of the dizzying pace of life, and the union weakens little by little until it breaks, and thus more and more separations and divorces occur.
