[K. in Cleveland]

OK, once again while watching tv (I swear, I do more than sit online and watch tv!) I saw a morning talk show with an interesting subject.
One one side was an author who writes in her book that one should never admit they were involved in an affair to their mate.
On the other side was a couple, a man who was engaged in an affair, who told his wife.. who had suspected but was getting denial from hubby.

The author argues that it will only create mistrust and tension between partners... she goes on to say if an STD issue came up from the affair you need to be responsible and say something to your mate. However beyond that it just creates a mistrust that not admitting anything would leave alone. If you've quit the affair, why bother hurting your mate?

The gentleman and his wife argued that his honesty was the best thing that happened to their relationship. She had suspected something was going on. He was swearing nothing was. She feels maybe she's going crazy, or is too paranoid.
He comes out and admits, she feels better that she's not paranoid, they work on the trust issue, and their intimacy level sky rocketed because now all communication is more open and honest.

So my question is Would you tell?
PS, the poll is anonymous
