Is it possible for love to sustain its original flame? How do eroticism, desire, and the strive for renewal play into love? Why do coldness, cruelty, jealousy, and betrayal appear in a couple's life? Is it possible to prevent their emergence? Does love die? Or can it burn forever? The renowned Italian thinker and psychoanalyst Massimo Recalcati discusses these questions in his book.
