Okay, well I was talking to my friend today and he says that he "commandeered" his sisters facebook account and went on it. Reading her messages and well, he found a chat log of his sister and one of my good female friends boyfriend flirting with her. That and he over heard his sister gossiping to her friends that this guy flirted with her, kissed her, etc.
Now, he has not actually presented me with physical evidence of this happening and hearsay is no valid evidence, so as of now I must disregard this as just hodge podge.
So, my question is this... if he does provide me with solid evidence of cheating, should I tell my friend about this?
As of now, I feel that I should take an isolationist stand point, be as America was when WWI broke out, not to entangle myself in "European Affairs", in this case European Affairs being the relationship scene. So I am taking a stance as of know, even if i do get evidence as just paying no attention to this.
Am I doing the right thing? What would any of you do in this situation? As someone who cares about my friend, should I tell her? Or should I let her have as much happiness as she can and let her find out about this herself?
