Input: Ill spare the details. I do not know this couple, they are a friend of a friends. All I know is that they are engaged and the guy has been cheating on his girl with one of my close friends and allegedly multiple other women. On one hand I feel like since I know nothing about these people I should stay out of their business, but on the other hand I have been cheated on and if I were in her situation I would be grateful if a stranger provided me with this information for me to investigate.

going out of my way to tell this girl that shes being cheated on
