Do you agree with the statement ignorance is bliss?
Example: Your SO has an affair that you never find out about. At the time of the affair, you were going through relationship issues that you have since worked though and the affair has ended. Your SO deeply regrets the affair and does not want to damage your current relationship by confessing it to you. Are you the type of person that would want to know about it even though it will be hurtful or would you rather not know since it is in the past?
Assume there is no chance that a similar situation will ever occur in the future.
