A/N: Sorry for the very long wait!! But I won't ever leave my stories undone, even if it takes forever to complete them. Thanks guys!

Three months later…

Olivia fixed her hair as she drove to Peter's place. She finally had the day off. She didn't see him for more than a week and they didn't even speak. Olivia figured it was because he was busy also.

She parked her car in front of his building and got out. She still had the key he gave her.

Olivia fixed her t-shirt and went up the stairs. She unlocked the door and let herself in, which she soon regretted.

She instantly heard noises coming from Peter's bedroom. She raised an eyebrow and slowly went to his room. The door was closed. She opened it and in instant she felt her whole body fill with rage.

Peter was naked in bed with a blonde woman. He instantly looked over and looked shocked. "Olivia."

Olivia shook her head. "Don't bother." She turned around and left.

Peter quickly got out of bed and pulled on his jeans. He grabbed his zip-up hoodie and ran after her. "Olivia wait."

"Fuck you." She spat out and stormed out of his apartment.

He pulled on his shoes in a hurry. He ran out of the apartment and pulled on the hoodie. "Olivia please. I'm sorry."

"Don't bother Pete. It's over." She answered.

"Can you let me explain?" He ran in front of her.

"Explain what? That you were fucking someone behind my back? I understand it completely." She tried to walk past him.

He stopped her. "I didn't. I thought we we're broken up."

"Just because I don't see you everyday doesn't mean we're broken up Peter. We're not in high school. I do have other responsibilities then to be your girlfriend."

"I know." He answered. "I'm so sorry. I haven't heard from you in a week. What was I supposed to think?"

"You didn't even call!" She yelled and pushed him out of the way.

He quickly followed. "I did. I called and left a message. You never called me back."

"I was busy!" She yelled back and kept walking down the stairs.

"And that's my problem?" He questioned. "Olivia, c'mon. Look, nothing happened."

She turned around to look at him. "You're going to lie to my face now also?"

"Nothing happened." He whispered. "Honestly."

Olivia shook her head. "I can't deal with this Pete. My life is complicated as it is. You we're supposed to be the stable part. Not anymore."

"Olivia." He took her hand. "I'm so sorry. I honestly didn't know what we were anymore. I hardly heard from you. And when we talked on the phone it was like we were just friends. Not dating. I didn't know."

"So how long did you give it until you slept with a new girl huh? Hour? Two days?"

"I didn't sleep with her." He answered.

"But you were going to." She answered. He didn't answer. "Exactly." She turned around and left the building. Peter stood there and just let out a deep breath.

-------------------------------------------------------------------------------------------------------------------

Olivia and Casey sat in Olivia's apartment and ate ice cream.

"He was a jerk anyway." Casey assured her. "All men are."

"Your boyfriend isn't." Olivia took a big scoop of her chocolate ice cream and then some of Casey's strawberry.

"Well not all guys can be perfect." Casey smiled at her. "You and Pete broke up before. You knew it was coming."

"I know. I just never thought it would be because of this reason." Olivia shrugged a little. They heard a knock on the door. Olivia glanced over at it.

"I got it." Casey got up and went to answer it. She opened the door and Pete was standing there. "Can I help you?"

"Where's Olivia?" He asked. Both knew they never got along but their fights were always playful. Not anymore.

"Not here." She answered. "She went out on a date." Casey answered with a smile. "Where's your girlfriend?"

Pete rolled his eyes at her. "Let me talk to Olivia. This doesn't concern you Casey."

Casey leaned on the door so he couldn't come in. "Oh yes it does. Leave."

Peter shook his head and pushed her hand off the frame of the door and went in. Casey rolled her eyes at him and followed.

Peter spotted Olivia sitting on the couch. "Can I talk to you?" he glanced at Casey. "Alone."

"Whatever you say to me you can say in front of her." Olivia answered.

Peter looked at Casey standing there. She nodded. He shook his head and went to sit on the coffee table to face Olivia. "I'm really sorry."

"You should be." Casey chimed in.

Peter gave her a dirty look and ignored her again. "Look Olivia, I know you might be mad at me-"

"Might? She's mad at your alright."

"Casey." Olivia warned. Casey got quiet.

Peter took a deep breath and kneeled down in front of Olivia. "Even if you're mad at me and you have every reason to be but I still want us to be friends."

"I can't do that." Olivia whispered. "I trusted you."

"I made a mistake ok? I didn't know if we were still dating. I know how you just dump guys without even warning."

"No I don't." Olivia snapped. "I'm just busy all the time. It's not my fault."

"Ok." He nodded. "I know it's not. But I didn't know ok? I just want you to know I would never intentionally cheat on you. You're an amazing woman."

Casey rolled her eyes. "Excuse me; I have to go puke my guts out."

Peter ignored it. "That's all I wanted to tell you. I don't want us to see each other and hate each other's guts across a room. I don't want to end this badly."

"Oh cry me a river Justin Timberlake."

Peter looked up at Olivia's best friend. "Can you just shut up for one second? Please?"

Casey crossed her arms on her chest. "Time is wasting buddy."

Peter shook his head and got up. "Are we ok Olivia? I know you dumped me but I don't want you to hate me."

Olivia nodded. "We're fine. I don't hate you."

"I hate you." Casey spoke up cheerfully.

"I hate you too." Peter responded instantly. "Bye Liv." He nodded and walked past her. "Bye pest." He mumbled to Casey.

"Bye cheater." Casey called back. She closed the door behind him and locked. "I can't believe you forgave him."

"What was I supposed to do? Hold a grudge against him even if we won't see each other again?"

"Yes." Casey sat down by her. "Always."

Olivia shook her head. "Took a lot of balls to admit he was wrong."

"Oh god, go wrote a poem."

Olivia smirked. "Shut up. Just because you're not the romantic type doesn't mean the rest of us can't be."

"Not 'can't'. Shouldn't." She corrected. "I know better, I have more fun."

Olivia smiled. "At least I learned a lesson; don't date guys you dated before."

"Only use them for sex." Casey grinned proudly. "So when you getting a new boyfriend? I need someone else to hate now."

Olivia laughed a little at her best friend and turned back to the ice cream. She was sort of glad this ended. She knew better then to date someone she obviously couldn't collapse her schedule with.

The End.

A/N: Not every story has a happy ending. At least Olivia learned something! LOL Please review!
