I saw this article and it presents a rather interesting ethical dilemma. The question is..."How many times will this guy have sex with his fiancée before letting her know what he found out?". https://www.marketwatch.com/story/m...be-a-fraud-and-liar-11632325714?mod=home-page
Ooops! MarketWatch only allows a certain number of articles to be read by non-subscribers each day. I was at my limit and could only read the headline. From the headline, it sounded like he found out relationship killing information without her knowledge.
If I learned deal-busting info, I would confront ASAP. However, I know some guys who would keep that nugget in their back pocket and continue the relationship.
