Post Infidelity Stress Disorder (PISD), also known as betrayal trauma, is a condition that affects individuals who have experienced infidelity in their relationship. It is characterized by a range of symptoms that can significantly impact an individual's daily life, including their ability to function in their relationships, work, and other important areas of their life. The development of PISD is often related to the severity of the betrayal and the individual's personal history of trauma.
