To heal from an affair, both partners must be open and willing to work through intense emotions like anger, betrayal, and grief. The hurt partner needs to freely express their pain, while the unfaithful partner listens without being defensive, validates the hurt felt, and gives a sincere apology that shows understanding. Rebuilding trust is a long process that requires transparency, tangible trust-building actions, and acknowledging that the hurt partner may periodically reopen discussions as they process the trauma of the betrayal. Professional help can aid recovery if issues resurface over time.
