Ok, so I have a friend, lets call him Bob. Bob and my best friend John live together. Bob is dating a nice girl called Wendy. Wendy is awesome, seriously. I'm married btw, so im not into her. Anyway, I drove John home from a party tonight, noticed an ex gf of Bob has her car parked out the front. Walked inside to get a glass of water, door to Bobs room is closed and I hear girly laughing. Ophelia is having a good time, but I don't think they are sexing. Do I tell Wendy? P.S. I know that Wendy and Bob will probably break up anyway because he's a cunt to women - should I be the reason they break up. Plz give me more than a yes / no.
