Am I obligated to tell someone if I know their partner is cheating on them?
I know someone who though I have not been close with them, I care for as a friend. I know they're a very good person and they do not deserve what they're getting from this girl. It's a crazy coincidence that I even found out that this girl is cheating on him. Do I find some way to tell him or just leave it be
EDIT: Consider that I will likely find a way to tell this person anonymously. I'm not about to get myself all up in his drama. I just feel bad for the guy.
