A friend of mine has been having an affair for the last 4 years. My husband and I are also friends with her husband. Over a year ago, an aquaintance informed my friends husband of the affair and I think he has just chosen to live in denial. All of our friends are aware of the affair, but nobody wants to say anything to her husband. It's gotten very awkward, since we know for a fact the affair is still going on. However, we also know that the husband (at least at one point) was aware of the affair. I would appreciate any feedback on how you would handle this situation.
