Husbands and Wives: If Your Spouse Is Having an Affair:

“Cling to the promise that — with God’s help — even the most broken marriage can be saved.

Remember, nobody wakes up one day and suddenly decides to have an extramarital affair. A person has been unfaithful in heart and mind long before he or she begins an affair.

Be patient. It takes time to begin to rebuild trust, love and commitment.”

These are some good prayer points. However the “Why” needs to be directed to God.
