Last night, my gf got together with her female friends and got shitfaced - posted videos and pics of herself spilling alcohol everywhere and top less with only a bra on on her snapchat story.
Understandably, I was pissed - my friends saw all this on snapchat too. Initially, before the get together, she had told me there would be no males there. Today, she called and apologized, and told me there were two guys who she did not know were coming beforehand - they smoked weed and left, according to her.
While I am fairly certain she did not do anything with these guys, how do I make it clear to her that I don't tolerate this?
