The OW doesn't necessarily disappear at the end of replay. In many instances, the OP is still hanging in the wings throughout most of the crisis. Unfortunately, some hang around until the person in crisis has taken the final step to return to the relationship with his/her spouse and will try everything in their power to get their partner back.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
