Elsewhere on the board, someone has said that it's weird not to tell one's spouse or partner about something that someone else has asked you to keep confidential. Do you agree?
If I confided in a friend about something serious (and, importantly, told them it mustn't go any further), I'd be furious if they told their partner. They are not one person, to me. They might be quite different personalities. I might trust my friend to understand/not to judge, but not their husband/wife. And how do I know the other half won't blab outside the relationship?
Do you tell your partner everything that you're told? Do you expect total confidentiality from friends or do you assume they'll tell their spouse?
