I fucked up

So I need advice! 
My boyfriend and I have been talking about trying things out sexually. My boyfriend and his best friend discuss having a threeway. His best friend is basically one of my friends ex that still lives together in her family's house. We are all over and my boyfriend and his best friend buy more alchol than usual and I drink a lot... End up sucking both of them up in her house. Boyfriend ends up hating the fact I'm being sexual with someone else and it all goes wrong...my friend finds out ....She doesn't even want to talk to me about what all happened... Should I just give her time? It also matters because she was continplating on getting back with him.
