★Setting boundaries was never so easy.

Why do we find it difficult to set boundaries? The idea of romantic love or the belief that they will stop loving us if we say "no" are some of the reasons. This is why we find it so difficult to do it, and when we do, we feel guilt, fear or anxiety.

The truth is that putting up barriers in relationships is as necessary as placing them at the side of the road: they help avoid accidents.

However, it is not always positive or healthy: It is how those boundaries are communicated that helps us to improve our relationship with others and with ourselves.

In this book, we will learn how to create more full and honest relationships, in which we feel more respected, loved and, above all, free to be who we really are.

Her books include practical examples and exercises that allow readers to apply the concepts immediately.
