Agree Never. Quite possibly, this is the cruelest thing that you could do to someone. Particularly when you don't understand it or only know part of the truth (at best), anyway. Let people live; let people learn.
Relationships last longer when no body knows your business. ~ plus it's not like it will be kept a secret.people you don't even know will know all about you and what goes on in your relationship, like my bff for example :p
Things will kill your relationship: insecurity, trust issues, jealousy, lack of communication & assumptions. I just witnessed this in my life. It only took 5 months.the shortest relationship I've ever had.
