So last night I was at a fire with my good friend and a few people. Everyone was drunk and it was a chill time, the only bad part about it was his ex girlfriend was there. They have been broken up for sometime but they still have feelings for each other, they wont admit to it but its pretty obvious. So we were getting ready to go to bed and set up a tent. His ex girlfriend was in the tent next to us with some kid that I am pretty good friends with but he can be a douch sometimes (this kid is in a relationship.) Someone tells me to go into his ex's tent for some reason which I cannot recall but anyway, I walk in to the tent and my best friends ex is giving this other guy dome. I have no idea what to do, should I tell my friend or should I not. If I tell my best friend his ex was giving some guy head the word would spread like a wild fire and the kid who was getting dome would get dumped right off the bat. But if I don't tell my friend I have to live with the guilt of not telling him for the rest of my life. Fellow NS'rs, what would you do?
Spark notes: My best friends ex was giving another guy head and I walked in on it. What do I do?
To the people that know me in real life I will kill you if you tell anyone.
