After infidelity, why do some couples work it out and others don't? 

The answer is in rebuilding the trust that has been broken through addressing the trauma symptoms, eliminating secrets, creating transparency, eliminating denial, and addressing shame.

Researchers have discovered that the part of the visionary brain becomes more active when an individual with PTSD talks about their traumatic experience. 

Brainspotting enables an individual to access their midbrain. This part is responsible for instinctual survival, like defending or fleeing threats. Brainspotting incorporates vision and midbrain stimulation to help individuals recover from PTSD. A counselor uses bilateral stimuli, and a fixed visual point to activate specific brain areas that can lead to trauma-healing during a brain spotting session. 

Individuals are asked to place headphones that play a sound or music in alternating ears. The midbrain is bilaterally stimulated and activated for treatment by alternating the ear in which you hear the sound. A counselor will then ask the person to think about a particular traumatic event or memory they want to work through. 

In keeping with this memory, the person finds a natural place to look at while paying particular attention to body sensations. Although this process may seem simple, it has profound effects on the treatment and ability to overcome different traumas types.
