If someone you know is sleeping with a married person. Would you tell their significant other? Or would you just let them keep going on their lies?
Most Helpful Guy
I wouldn't bend over backwards to help them hide it but I certainly wouldn't tell. There is no point, the SO probably already knows or suspects anyway (especially it that SO is a wife), it isn't any of my business anyway and all 3 people involved will hate you for doing it (if you think the SO will thank you for telling them the truth, dream on, you just brought their life crashing down on them, rational or not, they're gonna hate you).
These things play out one way or another by themselves, best thing you can do is stay well clear.0
