Does the rule "What happens in Vegas, Stays in Vegas really apply???

My friend and I went to Vegas for a trip and we left our gfs at home. Well me and my friend got a lil drunk and we met these twins and we all went back to their hotel room. Well needless to say they wanted us badly and my friend was all for cheating on his girl but i wasnt so i left and went to bed in my room. I dont know for sure if he cheated on her or not but I feel bad for his gf cuz shes a total sweetie. What do i do?

Ya I understand its a guy thing to not say anything. I prolly wont say anything anyways but if his gf asks me shes gonna know if im lying. Shes really good at that. I feel he wanted me to cheat as well so wed have each others backs on the situation.

One thing, Good for you for not cheating on your gf. that is the best thing to do is not to cheat on them. But you should tell your friends gf what he could of done because she has a right to know about this. And I mean come on what if it was you who were in her postion and did not know if your boyfriend(if you were a girl)/girlfriend was cheating on you. I mean you would want to know what your bf/gf was doing. I know I would want to know. So go and tell her, she does have a right to know.

Unfortunately, it's not your place to say anything. You can if you really want, but you'll just end up ruining your friendship with your buddy (who has questionable judgment anyway) most likely.

Man up and forget about it. What is wrong with you? You want to narc on your buddy? You are here by kicked out of the Man Club.

Does apply for me.
