Paulo Coelho said this quote
“ Millions of couples out there practiced the art of sadomasochism every day, without even realizing it. They went to work, came back, complained about everything, insulted their wife or were insulted by her, felt wretched, but were, nonetheless, tightly bound to their own unhappiness, not realizing that all it would take was a single gesture, a final goodbye, to free them from that oppression. ”
