Dissociation is a psychological defense mechanism that can occur in response to overwhelming stress or trauma. During dissociation, a person may feel disconnected from their thoughts, emotions, memories, or even their own sense of identity. While dissociating, individuals might engage in actions or behaviors without a full awareness of what they are doing or the consequences of their actions.
People experiencing dissociation may have difficulty recognizing the full extent of their actions and decision-making, especially during or immediately after the dissociative episode. They might feel disconnected from the reality of the situation and might not fully comprehend the impact of their behaviors on others or themselves.
If your friend has an undiagnosed Borderline Personality Disorder (BPD), it's essential to understand that BPD can also contribute to emotional dysregulation, impulsive behaviors, and difficulties with interpersonal relationships. These factors, combined with dissociation, can lead to actions that the individual may later regret or struggle to understand.
It's crucial for your friend to seek professional help from a mental health specialist, especially if they suspect they have BPD or are experiencing dissociation. A proper diagnosis and therapeutic support can help them gain insight into their actions, manage their emotions, and develop healthier coping mechanisms. Additionally, couples counseling could also be beneficial to address the impact of the infidelity on his relationship and work towards healing and understanding.
Encourage your friend to reach out to a mental health professional to discuss their experiences and feelings in a safe and supportive environment. Remember that diagnosing a mental health condition should be done by a qualified professional after a comprehensive evaluation.
