What Should I Do?

Apologize

It's on Sunday. Shelly is been warned by Georgia that she is going to be killed by her best friend. She calls Jessica directly after she ate breakfast with her parents.
................
Hey Jess, it's me. Shelly.
Fuck you. I know everything.
Um... what?
We're meeting right now at our high school, at the basketball court, got it?
Um yeah? But I don't understand why you are so mad?
You will see...
They meet behind the high school. Shelly is very scared. Far away, Shelly can see Jessica. Her blue eyes turn to dark eyes, which it looks like she's been in a horror movie. 
Jess... I...
Shelly... I know you did and I'll be thankful for ruining my fucking life. Don't you think I'm so hurt about this shit? I broke up with Ashton for a week ago, because of you. You fucked my childhood friend as an accident, but it seems not because you were fucking drunk that night. So you did everything that you want to behind my fucking back...?! Shelly, I'm abused... Jessica begins to cry.
I'm abused Shelly, you know it!?
No... I actually don't? You didn't talk to me in a while.
YEAH, because I heard you moaning in MY BEDROOM! And I heard Ashton too.
No... no, you didn't? Shelly is getting nervous.
Yeah, I was so drunk that I can't handle. But sometimes, when I'm getting drunk. I can recognize voices from persons I know. At that night, you slept in my bed and Ashton went out of the room. I saw him naked in my room. I was shocked. My sister took a picture of you and Ashton, where you were been dating, you remember?
Oh no... Jess, it's not what you think.!
Then what I think it's about?
They keep that conversation in a long time, and then after, Jessica is not ready to forgive Shelly of her own dumbness.
Jess, listen! Here's the truth.
Jessica is listening.
Ashton told me that he loves me, right? I've been crushed on Ashton since you met him for over two years. I can't dare to tell you that I was in love with him. At that time, it begins so weirdly and it's not even normal than ever before. Then during your party, I had heard from him that he was tired of you because you're the worst girlfriend. I'm sorry for that night. I was so drunk, I didn't think about it so clear. During we had... yeah sex, he began to be very weird that he would try me. I didn't accept it, but he stays on again and again. I was in love with him, I can't no. I'm so sorry. I was an accident. You're the best girl and I support you in so many years. I do.
Jessica cries and she is going to be very harsh.
I can't forgive you, Shelly. It's over. Go away. Don't ruin my fucking life again, you understand? It's over.
Jessica leaves behind her back. Shelly is done with this conversation. She feels so sad that she can't take herself on control. Is their friendship dead, or not?
