It's an informal book; I will call you an asshole, we will talk about Tinder, jealousy, other girls, getting drunk to forget and making her feel sorry for you by sending her messages, groveling or even going over to her house with flowers like an imbecile.I'll try to touch your pride to make you react. I will make an "over my dead balls is this going to go on like it is now" come out of you.Before you even buy the book, you should know that you will only get out of this shit on the base of pride and self-love, putting your well-being above all else. And you will realize that it's not selfishness, but rather on the contrary: to love others, you first have to learn to love yourself.It's a short book and quick to read; I don't want to annoy you with words. It's not about entertaining yourself on a long trip where you don't know what to do. It's a manual of steps to follow in order to be happy and you will read it in a good mood and smiling.Believe me that if you follow everything in the book to the letter, you will soon recover and you will do so in a healthy manner and having learned a lot to continue being happy in the future.
