Somewhat related, I never tell a girlfriend anything that I'm not comfortable with her passing on to her husband. I may not have as close a relationship with him as I do with her, but I will never ask her to keep anything from her husband. I have a friend who has asked that of me once or twice, and I was really uncomfortable with it. I trust that my friends aren't going to go blabbing the details of our conversations to their husbands, but when I decide to share something, I decide that I'm okay sharing it with both my friend and her husband.
