My brothers girlfriend is cheating should I tell?

Hopelessgirl92
Both she and my bro are 25 and have been together for just over 9 years. I received an e-mail from someone who has sent me evidence that she has been cheating on him for the past 5 years every other day with his BFF. I talked with her about it and She convinced me not say anything. I've been knowing about this since it first happened in 2011 up to this current day its stl going on Most of the time it happens it when he's out of town town or at work. I know that she cheated on him last night and today. I have NO idea how to handle this. Should I say anything to my brother or just let it work itself out and he will figure it out soon enough?

The only reason I have thought of telling is because people have said that he "deserves to know". I think he is better off not knowing, will save him a lot of hurt now. I truly believe that in the end people's true col
