CNN provides a number of insights into infidelity (of course in the wake of Arnold Schwarzenegger and Maria Shriver), and what comes next. There also are 3 tips for when you discover an affair.
Amy Wilson writes (excerpt):
[Dr. Steve Solomon] gave this advice:
1) Don’t rush to make any big decisions, especially irreversible ones.
2) Don’t tell your children. Especially if they are small.
3) Take care of yourself. This will ensure the patience and calm you will need.
