And human beings feel that shift before they fully understand it. Psychologists believe the brain constantly tracks emotional reciprocity in relationships. When attention, curiosity, and responsiveness decrease, people often experience subtle feelings of distance, irritation, numbness, or loneliness before they consciously label it as ‘falling out of love.’ This is also why many people describe relationships becoming ‘roommate-like.’ The affection may still exist, but the emotional fascination starts fading. Without curiosity, relationships can begin feeling emotionally static.
