Have you considered the many situations that spying might uncover? Can you imagine the worst thing you might find? Predict what your response will be to the worst-case scenario. Are you ready? Here are some specific questions to ask:
1) Do I have friends I can count on for support if I discover the worst? Do they know I might need them? Have I told them exactly how they might help me? Do I have the capacity to stand back from the deep emotions and not get mired or lost in destructive thoughts and feelings?
2) How have I handled emotional pain in the past? What if it gets almost unbearable? If I encounter the worst possible emotional hurt and pain, do I have a therapist I can contact immediately and see soon to help me through the rough spots?
3) You see the signs of a cheating spouse. What will be my strategy for what I find? Do I have a strategy for the different scenarios? Do I have a strategy to confront or not confront my spouse? How, when and under what circumstances will I confront him/her?
4) What kind of strategy will I have for self-care? What will I need to do to keep myself functioning somewhat effectively?
5) Do I have a coach or an objective someone who knows about cheating husbands and cheating wives and who can help me develop strategies and goals for confrontation and self-care? Someone to keep me focused and working on these strategies and goals?
6) Do I know what kind of affair I might face? Do I know the prognosis for that kind of affair? Have I educated myself about affairs and what I must do to effectively resolve and move through this crisis?
