Marriage Rx: Should I Tell My Friend's Husband That She's Cheating?


Marriage Rx CM SantosIn a recent New York Times column by someone calling himself  “The Ethicist,” a reader asks if he should continue to conceal his friend’s long-standing extramarital affair from her husband. The columnist advised the reader not to reveal the affair because the reader was closer friends with the woman than with her husband. Here is a shortened version of the original question and our very different answer.

Question: I am a man (if it matters) and friends with a married woman, ‘‘Jane,’’ and her husband, ‘‘Peter.’’ The friendship is more with Jane than with Peter. Jane is having an affair with ‘‘Martin,’’ whom Jane has known most of her adult life. I know about the affair because Jane confided in me years ago. Jane thinks Martin is her true life’s ‘‘soul mate,’’ and I think she may be right. Peter does not know about the affair. If he knew about it, I think he would divorce Jane in a minute. Jane and Martin likely will never be together. Martin is married with children, and he lives in another country. Martin visits the United States once or twice a year on business, and during those visits Jane and Martin spend a weekend together, usually in a hotel. Jane lies to Peter when this happens; she tells him she’s away on a business trip. What should I do? If I continue to be friends with Jane and Peter, I end up in some small way lying to Peter, who is also a friend. -Name Withheld

Answer: The quandary is that Jane is betraying her husband Peter, but if the reader tells Peter about the affair, then the reader is betraying his friend Jane. It’s natural for most people to want to run far, far away from such a sticky situation.

The pros of telling Peter about the affair are (1) Peter will know the truth; (2) the reader will no longer have to deceive or lie to Peter; and (3) Jane may be motivated to stop the affair. The cons of telling Peter about the affair are (1) it’s really none of the reader’s business; (2) Jane told him about the affair in confidence; and (3) Peter might divorce Jane once he finds out.

The New York Times columnist concluded: “you are in a deeply compromised moral situation — one in which the cure is worse than the condition. As is so often the case, there’s no way out from under the net. … The best outcome often has something deplorable about it.” In a word, balderdash (or something else that starts with “b”).

There is a way out. It doesn’t involve the reader talking to Peter, but it does involve him talking to Jane. It’s called fraternal correction, or admonishing the sinner, and it’s a spiritual work of mercy. We found a great blogpost setting out a few ground rules for fraternal correction, and this situation meets them all.

1. Is it serious? This one is easy. A long-term extramarital affair is extremely serious.

2. Will it resolve itself? Jane has been able to hide her affair from her husband for years. She apparently has no motivation to stop her relationship with a man she feels is her “soul mate.” She doesn’t seem to mind involving her friends in the deception either. There’s very little chance that the situation will resolve itself without intervention.

3. Will it be effective? The strength of the reader’s friendship with Jane actually counsels in favor of his being able to reach her. If she cares about her friend, she will understand that he does not want to deceive or lie to her husband. Perhaps perceiving it  through her friend’s eyes, she will see that deceiving her husband is not the right thing to do.

4. Do you have the best shot at getting the point across? The reader may be one of the only people who knows about the affair. Therefore, he may be one of the only people who can convince Jane that her behavior is bad for her marriage.

So, our response in a nutshell is that the reader ought to tell Jane that he doesn’t feel comfortable lying to her husband about the affair. He can explain that she is putting her marriage at risk by continuing the affair and that treating her lover as her “soul-mate” is preventing her from seeing her husband that way. If she stops the affair, she may just find that her husband can be the “soul-mate” she’s longing for.

  1. Did you ever think that the husband may know about the affair. Maybe he cheats as well. Some couple have what is called an open marriage. I personally think people should not interfere in such things . What happens between a couple is really their business not the world’s. As to correcting the sinner, Jesus also said let he who is without sin cast the first stone and take the beam out of your own eye before you take the mote out of your neighbors eye. Adultery is something a couple needs to sort out not a friend who has no stake in the marriage

  2. I agree that someone else’s marriage is none of anyone else’s business. But Jane has explicitly made it someone else’s business, when she chose to lay the burden of her sin on her friend. When someone attends the wedding of a friend or is friends with someone who is married, there is a moral obligation laid on members of the community to support the marriage.. By not speaking to Jane about her infidelity, the friend is not supporting her marriage, he is supporting her infidelity. And has become part of the deception surrounding her husband. Really despicable, if you ask me. Basically Jane is forcing her friend to lie by omission to the cuckholded spouse and become part of a community of support for her sin. The friend should have no part in it. No, he shouldn’t tell the husband, but to say nothing to Jane, when she had explicitly told him, is deeply deeply wrong.

  3. I agree with Mari’s comment. An open marriage is not a Catholic marriage. Consenting before the wedding to an open marriage is actually grounds for an annulment.

  4. I’m the neighbor who DID tell the neighbor that her husband was cheating on her. As far as taking the “its none of my business route”, its a cop out. When your children literally are growing up with THEIR children, it DOES effect you and your entire family. I presented the situation calmly as the man next door was bringing another woman into the home. Would you rather I tell, or my children tell YOUR children about the highly OBVIOUS situation occurring right next door. The problem with today’s society is fear of doing what is right an just. And that is NOT Fear of the Lord. Its cowardly to take a detour on the “not my business route”.
