In this short YouTube monologue, the speaker explains that people often stay in a relationship not because of love or personal weakness, but because of the sunk‑cost effect: the time, energy, hopes and effort already invested. The brain’s aversion to losing what has been given makes individuals justify silence, minimize absence, and adapt further, turning the relationship into a source of anxiety rather than fulfillment. The speaker emphasizes that this is a psychological mechanism, not a matter of value or strength, and urges viewers to watch a longer video for a deeper explanation, offering to send it to anyone who comments the word “cerveau”.
