LEV532 The demand to protect confidential matters applies not only to public authorities like judges but to private individuals as well. The Torah prohibits spreading not only falsehoods about other people (sheker, "lying") [this verse] but also true facts about someone else that they have no need to know--in other words, rekhilut (gossip) [Leviticus 19:16]. The Talmud takes this further, insisting that even if there is no harm intended or anticipated, a person may not reveal a private conversation to an outside party, unless the original speaker gives explicit permission to do so. B. Yoma 4b. This rule restricts the information shared even with a spouse. Indeed, in marriage one may and should keep some of one's own thoughts or actions to oneself, for despite the physical and emotional intimacy of the relationship, married people continue to need and deserve a degree of privacy. People clearly have the duty to inform their spouses about anything that will have an impact on their lives in the present or future, but when there are no such practical implications, spouses should not be told or reminded of past actions or of present or past thoughts that will only upset them. For that matter, as a general rule, spouses have no obligation to tell each other everything they have done or thought and, conversely, they do have the right to be downright uninterested in some aspects of the other's life. Some things, even in marriage, may and should remain private with the individual.
