Is it my fault?

My friend and I decided to chill with this couple , kick back loosen up and have a couple of drinks . Things went left when the dude pulled out coke . Me being me I got up and went outside on the balcony trynna get service to get a Uber for me and my friend . The Uber was 8 mins away . 8 mins never felt so long . My friend is drunk snorting lines & shit she comes out side with the dude dick in her hand jacking him off telling me stop being a party pooper so I told him can he excuse us real quick I told her to snap out of it the Uber is on it’s way she’s like Ight girl ima put my shoes on . I walk inside my friend is naked kissing the girl & jacking him off at the same time I’m like GIRL LETS GO THE UBER IS OUTSIDE he grabs her and say babe doesn’t wanna go any where . I’m like please let’s go she’s like Ight ima go with you . She puts her clothes on the dude whispers in her ear . AND SHE WENT OFF ON ME . Saying I wasn’t her mom she don’t have to listen to me. I’m like come on I’m not gonna leave you here like this your drunk and high off drugs please let’s go . She didn’t budge she started saying how jealous I was of her how I want her life . And I’m like please let’s go so I grabbed her tried to take her outside I DIDNT CARE IF SHE HAD NO CLOTHES ON we needed to go . THIS BITCH STARTED TO SWING ON ME screaming . So I let her go .
