Don't be disrespectful to your wife and/or the other man. Resist the temptation to call him names. Treat your wife with respect regardless of how you feel.
Expect your wife to be venomous toward you.

-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
