My wife had an affair for 7 years. She was pregnant with our daughter during the affair. Her affair partner is married and has a young child of his own. His wife does not know about the affair. The affair partner lied to my wife about being married for the first 4 years of their affair. I want to tell her for the following reasons: 1) I now carry a secret that I feel she should know as he is continuing to lie to her and I know what that feels like. 2) I want the affair partner to also have a cost for his actions and how he manipulated and lied to my wife for years. 3) I want the affair partner to be angry at my wife so as to reduce the risk of relapse. 4) My wife doesn't want me to tell her. Should the affair partner’s wife about their affair?
