It's really hard to tell you I'm sorry
I don't wanna break your heart again
It's really hard to tell you I'm sorry
I don't wanna see you cry again
It's really hard to tell you I'm sorry
Is there anything that I can do
It's really hard to tell you I'm sorry
I don't wanna break your heart again

Sorry by Sweetbox

Chuck stopped, his heart in his throat. There was that silky, brown hair that he loved to run his hands through. That firm, smooth ass from the hours she spent playing tennis. That horrible EX-boyfriend of hers. Or so he thought.

Chuck felt like he had been smacked across the face. Blair and Nate…together again? It seemed impossible. Two days ago, Blair had been lying in his arms on her bed, and now she was grinding up against Nate in some hotel? What the fuck was going on?

He resisted the urge to shout, or pull the fire alarm and drown the happy couple. Instead, he remained as cool as possible and slipped back down the stairs from which he came. If that was the way Blair wanted it, well…two could play that game.

Blair sat on the tacky, red leather couch looking smug. New Years was rapidly approaching and she was already starting the year off perfect – Nate and her were back together. By the next New Year, they would be celebrating in their off-campus apartment by having wild sex, and then maybe spending the next day studying in Yale's library. She smiled, feeling content and happy with her and Nate's future.

Serena danced over to the cheesy couch, looking radiant in her vintage, black and pink Armani dress. She plunked down next to Blair, not spilling a single drop of her Cosmo.

"Isn't this club great?" Serena shouted above the booming music. Pulse was the hottest new club in Manhattan, attracting only the hottest people. Blair and Serena decided it would be the coolest place to plan their big New Years Eve party.

Blair shrugged her thin shoulders. Ever since Serena started dating that weird, lonely boy Dan, the two girls had grown apart. Before her and Nate got back together, Blair was constantly annoyed by Serena's excessive happiness and ramblings about Dan. But now that her and Nate were as perfect as ever, Blair decided she could be civil. Besides, she needed Serena's help with the party.

"So…" Blair began awkwardly. "How are you and what's-his-face? Aaron? Brandon?"

Serena rolled her big, blue eyes. "Dan. His name is Dan, Blair. Stop acting like you don't know it!"

Blair made a face at Serena. "Honestly S, I don't know his name, nor do I care."

Serena shook her head, her blonde hair flying all over. "He's such a sweet guy…"

"Hey girls," Nate said, coming up from behind. He leaned over the couch and kissed Blair on the cheek. "You smell good."

Blair smiled prettily. "Thanks. You're late though."

Nate walked around the couch and sat between the two girls, and put his arm around Blair, pulling her close. "Sorry. Chuck had to pick me up in his limo because my dad was being a dick."

Blair stiffened and pushed Nate away. "Chuck is here? What the fuck?"

Serena leaned forward, chugged the rest of her Cosmo, and asked, "What's the problem? Chuck always helps us plan! He has great ideas. Too bad Dan couldn't come…"

"I don't remember inviting Chuck," Blair said, frowning. "I'm pretty sure I made sure not to invite him."

"Now sweetheart," Chuck said sarcastically, appearing out of nowhere looking devilishly handsome. "That isn't what you said last week."

He sat down next to Serena, looking hot in his True Religion jeans and white button up.

Blair shifted uncomfortably. "I don't know what you're talking about, but whatever. Let's get this shit down with." She pulled a pad of paper and pen out of her expensive bag, and then signaled for a waiter.

"But before anything – let's drink!"

"I don't know why the fuck I'm stuck planning with only Chuck," Blair complained. "And why the hell are we planning in a room at the Plaza?"

"Maybe he thinks he's going to get lucky again," Serena joked. "You would think he would be over it, though. That was like a month ago and a one time thing."

Blair looked away from her blonde friend, knowing she couldn't lie straight to her face. The Chuck thing had not been a one-time thing. It had been an almost every day thing for two weeks straight. And it hadn't just been some "thing". It seemed like it was something more. Something…serious.

But then Nate had come back into the picture and it was time for Chuck to get lost. Blair didn't want to risk her perfect relationship with Nate for a flaky, horny guy like Chuck who didn't give a shit about her. Or so she thought.

The two girls stopped in front of the Plaza and Serena looked at her diamond Cartier watch. "Oh! I'm late. Dan is going to be upset…"

Blair rolled her eyes. She was embarrassed by how head-over-heels her friend was for that loser kid. It was nauseating to listen to.

Serena kissed Blair on the cheek and ran off, waving. "Good luck with Chuck!"

"Luck," Blair mumbled to herself. "I'm going to need a lot more than that."

She walked slowly into the ritzy hotel, the doorman greeting her with a tip of his hat. "Nice to see you, Ms. Waldorf," he said, beaming at her.

Blair smiled briefly at him, feeling distracted. She couldn't figure out why they were meeting in a hotel, and refused to believe it was because Chuck thought he was getting some. He knew very well that her and Nate were happily together once again and that no one was going to come between them. Not again.

She drifted to the elevator and jabbed the button a few times, and boarded quickly and shut the door before anyone else joined her. Blair enjoyed riding elevators alone – unless she was making out with Nate in one.

The elevator beeped, and Blair stepped out into the hallway. Of course Chuck had booked a suite. She stomped down the hallway, feeling angry. Stupid, stupid Chuck. Stupid Chuck. Not attractive at all.

She banged on the door, surprised that Chuck wasn't creepily watching her from the peephole.

Nothing.

She knocked again, as hard as she could, without caring if she was disrupting other guests. Like they mattered anyway. When there was no response, Blair kicked the door with her heels. Nothing again.

Frustrated, Blair grabbed at the doorknob, wishing she could break it off. Instead of having to break the knob, she felt that the door wasn't even locked. Slightly embarrassed, Blair turned the knob and entered the room.

All the lights were off. "Chuck?" she called out tentatively. "It's Blair."

Blair stepped out of her heels, removed her jacket, and dropped her purse on the ground. She walked past the kitchen area and the sitting room, and headed for the bedroom, fully expecting Chuck to be waiting, naked with whipped cream and handcuffs.

She stopped in front of the door, seeing light underneath. She listened carefully; it sounded like a female was in the room. Deciding that Chuck must have some random girl on speakerphone, Blair burst into the room.

Chuck and some random slut lay on the bed, groping each other and panting like dogs. Blair felt sick. Her stomach twisted into knots and her mouth was dry as her mom's martinis. She tried to discreetly grab the doorframe, hoping it would keep her from falling over. What the fuck was going on?

"C-Chuck?" Blair gasped, her voice raw with emotion. "What the hell is this?"

"AH!" The girl screamed, finally noticing Blair. She ripped the comforter from under Chuck, trying to pretend that she had enough morals and virtues to be embarrassed by the situation.

Chuck sat up, looking calm. He stared straight into Blair's eyes and shrugged. "I forgot I told you to meet me here. I'm kind of in the middle of something…well, someone." He smirked. "Can we reschedule?"

Blair felt her stomach reject whatever food she had eaten that day, that week, that month. She was going to be violently sick in front of that skank if she didn't escape. Keeping her mouth shut tightly, she flicked Chuck the bird and stumbled out of the room, her eyes watering.

She grabbed her heels and her coat, forgetting her purse in her desperate rush to get far, far away. Blair hurried down the hallway, frantically searching for the closest public restroom, and continued to tell herself that she was crying because she was going to have to plan the party alone, and it had nothing to do with the fact that she felt like her heart was breaking in two.
