Nothing has more destructive or more creative power than love. Where does this strength in love come from? And how does it transform in different social conditions? How is love changing in the Internet era? The book by the famous sociologist and psychologist Eva Illuz has received resounding international success because it provides the key to understanding the changes that have occurred in the relationship between men and women in modern times. The reasons for the strength of love traumas should often be sought not in the depth of psychological experiences, but in the specifics of the social rules into which the modern individual is driven. Changes in the ways of self-perception, building one's own career, the formation of marriage markets, women's emancipation - the author carefully analyzes all this, skillfully turning to literary classics and the latest sociological trends. The book is intended for sociologists and psychologists, as well as for a wide range of readers interested in the psychology of relations between man and woman.
