My wife has always called him her 'brother', but I never really thought of him that way... We were more like friends or close siblings. So when he would come over during work hours or stay late because we missed the last train, there was no resistance from my side. But then one day, everything changed... I couldn't speak; I had to leave the room. That night, I decided to confront my wife about what happened. *Note: Content may vary depending on the recording method used.
