A/N: My first Klaine fic I'm posting on this site! This is going to be a 3 part fic. It's based around the time of 4x14 and 4x15, so I guess a spoiler alert is in order. But I have been planning this fic since before we got all those spoilers for ep 4x14, so it does stray a bit from them (don't be alarmed when you see that Kurt's date to the wedding isn't Blaine), but this is how I pictured things to go if Blaine and Kurt didn't go to the wedding together. I already have the whole thing outlined so the other 2 parts should be up soon. This part is full of angst (and a jealous Blaine), but I promise that parts 2 and 3 will make up for it.

I'd Do Anything for Love- Part 1

Blaine Anderson eyed the ground with his head hung low. He had absolutely no desire to glimpse up and observe everybody thoroughly enjoying themselves while he remained leaning against the refreshment table at Mr. Schuester and Miss Pillsbury's wedding reception. A couple of his friends—Tina and Sam included—begged him to join them on the dance floor, but he bluntly refused. He did not even want to sing with the rest of the glee club, preferring not to draw attention to himself.

He inhaled a sharp breath at the sound of a familiar laugh approaching him. For a brief moment, he truly believed that everything was exactly like it was six months ago. In that split second, he thought he was going to tilt his head up, gaze into a pair of blue eyes he knew so well, and press his lips swiftly against the ones smiling back at him. However, his reverie dissolved when he glanced up and realized his reality. The familiar laughter had belonged to Kurt Hummel, but he was not laughing because he spotted Blaine; his giggling was the result of a tall blonde boy pressed up against him whispering into his ear.

Blaine painfully reminisced the phone call. He could still hear Kurt's voice clearly in his head confessing he had found someone new. Furthermore, he vividly recalled Kurt boldly asking him, "How would you feel if I asked Adam to accompany me to the wedding?" Sure, it felt like Blaine was being repeatedly punched in the stomach, but his heart lightened slightly due to the fact that Kurt inquired Blaine's approbation. As much as he wanted to break down in hysterics, Blaine woefully agreed. After all, he's supposed to be friends with Kurt, and friends support friends, right?

At least during the ceremony Blaine could act like there was no problem because he was standing up with the rest of the new and old glee club kids, Kurt included. His gaze surreptitiously drifted toward Kurt repeatedly throughout the duration of the ceremony, but for the most part, he remained focused on the happy couple. Now that the spotlight had somewhat strayed away form Will and Emma, everybody was freely doing their own thing, and Blaine could not help but stare shamelessly at Kurt, whose arms were grasped tightly around Adam's neck.

Blaine clenched his fists and gritted his teeth, willing the rage bubbling up inside of him to remain at bay. He pivoted around to shift his focus back to the refreshment table, but he could not help but acknowledge the incessant laughter coming from the direction of Kurt and Adam. You told him this was okay, Blaine mentally told himself. He's not you're boyfriend anymore. He's allowed to date whoever he wants. This reassurance only made him feel worse.

He only turned away from Kurt when he heard a voice saying, "Dude are you going to be a party pooper all night?" Blaine found himself face to face with a genuinely concerned Sam Evans. "You've been moping around since we got here. What's your deal?"

Blaine dropped his head once more, remaining coy and muttering incoherently.

Sam eyed Blaine suspiciously before peering in the direction Blaine had been minutes before. He looked back at his friend sympathetically. "Does this have anything to do with Kurt bringing that guy?"

Blaine's head snapped up, and his eyes drifted over Sam before subtly moving towards Kurt. "No," he scoffed. "I told Kurt he could bring him. Why would I be upset?"
"Because you're still in love with him," Sam offered. Blaine's face fell at once, his eyes starting to glisten with tears. He let Sam continue. "You can pretend all you want that you've moved on, but you haven't. You can't help but think that maybe, maybe if you hadn't screwed up so badly, you'd be the one dancing with Kurt right now, and that's killing you inside."

A single tear escaped Blaine's eye and trailed down his face, getting caught on the corner of his slightly open mouth. "I want to move on, and I want to be okay with Kurt moving on," Blaine's voice got caught in his throat as he choked back more tears. "But I see the two of them together, and I can't help but picture him kissing Kurt a-and touching him, and it makes me sick. I mean, what kind of person does that make me? How does it make me look?"

"It makes you human," Sam said with affirmation. Sam and Blaine glanced over to see Kurt and Adam having a lively conversation with Mike and Mercedes. Adam's hand was settled intimately on Kurt's waist, and Sam and Blaine turned just in time to see Kurt laugh at something Mike had said and lean his head comfortably on Adam's shoulder.

Sam turned back to Blaine. "You and Kurt have been through so much together. You thought you were going to be with him forever. So of course seeing him happy with somebody else is going to make you upset." Blaine kept his eyes fixed on Sam and remained silent as his friend continued. "But this is probably just as hard for him as it is for you. He doesn't want to feel like he's rubbing it in your face that he's moved on and met somebody new, but he knows that if he doesn't, it's just going to hurt more. He wants to prove to you that he's still living. This is him telling you that he's trying to be okay and going on with his life; maybe you should try it too.

As Blaine wiped his stray tears with the back of his hands, he smiled up at his friend. "And you say you're not smart," he joked.

"Hey, sometimes I surprise even myself," Sam replied with a small laugh. After a moment's contemplation, Sam clapped Blaine on the shoulder. "Hey, come help me, Jake, and Ryder on this next song."

Blaine gave a hesitant smile. "No. No. You go ahead. I'll catch up with you later."

Sam knew better than to continue pestering Blaine when he was in this mood, so he gave his shoulder a gentle squeeze and went to join Jake and Ryder on stage.

Blaine was well aware that what he was doing wasn't fair to himself. He couldn't continue to stand here watching everybody enjoying themselves while he was feeling sorry for himself. It wasn't fair. There was still ample time to have fun with his friends, and Blaine was going to savor every remaining moment of this wedding reception, with or without Kurt.

Just as Blaine had made the decision to ask Tina to dance—he knew she had been deeply upset since he unabashedly rejected her advances—a voice said behind him, "You look like you're having the time of your life." Despite the fact that Blaine knew the voice, he'd recognize that sarcasm anywhere. He spun around so he was staring straight at Kurt.

"Is it that obvious?" Even though they were broken up, playful banter still came easily to Kurt and Blaine.

"Why aren't you up there with the boys shaking everything that you were graced with?" Kurt asked, gesturing towards the stage where Sam, Jake, and Ryder had started performing some bad '90's rap song that Mr. Schuester had picked out.

Blaine chuckled slightly at the ridiculousness of the number before turning back to Kurt. His eyes flickered down to Kurt's lips, but he abruptly moved them back to Kurt's eyes, praying that Kurt didn't notice. "Remember this time last year? Valentine's Day?"

Kurt gave a short laugh before replying, "Of course. You surprised me at Sugar's party in that adorable eye patch, we sang together, and then I dragged to the back and gave you a blowjob in a bathroom stall."

"Not one of our classier moments," Blaine admitted, blushing.

Kurt shrugged. "But it was still pretty hot." Kurt giggled as Blaine turned his head away, his cheeks turning an even brighter shade of red. Blaine looked back up to see Kurt staring directly at him. Once Kurt noticed Blaine catch his eye, he turned away quickly and cleared his throat. "But, uh, anyway, I heard that you've caught somebody else's eye."

Blaine gave Kurt a puzzled look as Kurt laughed, and then realized he must have been talking about Tina. "Oh. Yeah. That. I do kind of feel bad that I've been blowing her off all day, especially since I asked her to be my date."

"Well, the girl applied vaporub to your chest while you slept. I think it's good to teach her to keep her distance." Full of embarrassment, Blaine buried his face in his hands while Kurt continued laughing.

Before Blaine had a chance to say anything in defense of what happened, Kurt nudged him gently and said, "What is it? Don't think I haven't noticed you throwing yourself a pity party over here all afternoon."

Bashfully, Blaine said, "Nothing. It's nothing." His eyes fixed on Kurt, and, trying to sound honest and sincere, he added with a forced smile, "I'm great. Everything's great."

Being incredibly close to one another, Blaine knew that Kurt could sense the palpable lie lingering between them. "Blaine, come on," Kurt said. "I may not be dating you anymore, but I still know you better than anybody else. Please tell me what's bothering you."

As if on cue, Adam appeared from being Kurt and Blaine, put his arm around Kurt's shoulders, and said, "Hey guys! What'd I miss?" He shot a friendly smile in both Kurt and Blaine's direction.

Kurt reached up and patted that hand that was draped over his shoulder. "Oh, not much. Just catching up." He looked at Blaine, realizing, "Oh! I forgot that you two haven't formerly met. Adam, this is my best friend Blaine. Blaine, Adam."

Adam held the hand that wasn't around Kurt out to Blaine, smiling brightly. "So nice to finally meet you. I've heard a lot about you."

Blaine politely took Adam's extended hand, but he could no longer hide his evident vexation. Kurt referred to Blaine as his "best friend." Technically, that was the truth, but they used to be so much more than that. Blaine wondered if Kurt even told Adam that the two of them dated, and not just dated, but actually planned out their future together. Blaine wondered if Adam knew that his arm was currently wrapped around the love of Blaine's life and soul mate.

There were so many things Blaine wished he could say to Adam, but with Kurt standing right there looking content, he settled with a forced, "Nice to meet you too."

"So, Kurt tells me that you're thinking about applying to NYADA for next year," Adam said cheerfully.

Blaine made great strides to hide his overt animosity. He clenched his teeth, shot Adam a fake smile, and said, "Uh, yeah. Yeah, that's the plan."

While Adam continued talking, Blaine was having a difficult time comprehending what was being said. Instead, his vision was concentrated on Adam's fingers lightly caressing Kurt's shoulder. Blaine couldn't help but wonder where else those fingers had touched Kurt. He felt a hint of bile slowly creep up his throat at the thought and coerced it back down with a rough swallow. Blaine willed his eyes to look back up at Adam's face, attempting to cease his inappropriate thoughts.

Blaine only snapped back to reality when he heard Kurt call his name. "Blaine?" Blaine blinked hard and turned his eyes towards Kurt. "Blaine, are you okay? We seemed to have lost you for a minute there."

Blaine dropped his eyes to the ground and shook his head. "Uh, yeah, fine. Everything's fine. I, um, I'll be back. I just need some air."

Concerned and slightly puzzled, especially at the fact that they were outside, Kurt turned to Adam. "I better go see if he's okay." Adam nodded and Kurt took off in the direction Blaine had just departed.

Blaine struggled to wipe the angry tears streaming down his face as he heard the familiar cry of "Blaine!" from behind him. However, he failed to slow his pace.

Breathing heavily, Kurt increased his pace in order to keep up with Blaine. "Blaine, come on! Please stop! Talk to me."

Blaine came to a sudden halt and spun around, his eyes puffy and his cheeks blotchy from the crying. "I just don't know what the hell I'm doing anymore! I don't know what's going on!"

"Blaine what are you talking about?" Kurt asked, confused.

"You know, I thought I'd be okay with this. I really did. I really wanted to be okay with it." Blaine spoke slowly through his tears, trying to pick out the right words. "But I can't do this any more. I can't. "

"You can't what, Blaine?" Kurt's eyes started watering at the sight of Blaine so upset.

Blaine blinked, allowing a few more tears to fall, as he chose his next words carefully. "I can't just sit here and pretend that nothing's wrong while I'm watching you fall for somebody else."

Those words hit Kurt hard, causing him to take a step back. Openly crying now, Kurt whispered, "That's not fair." He swallowed before continuing. "You know, the one thing that I've always loved about our relationship, even before we started dating, was that we've always been honest with each other. You told me that you were okay with me bringing Adam today. I asked if you were completely sure, and you said you were."

"I tried playing the role of the supportive friend." Blaine was speaking louder now. "So you want honesty? Well, the truth is I can't continue acting like I just want to be friends when I'm still in love with you! I've never stopped loving you, and I don't think I'm ever going to.

Kurt's voice was now rising too. "You don't get to do that! You don't get to hurt me the way you did, and then, when I'm finally trying to pick up the pieces, completely shit on everything! I was wary to let you back in, Blaine, but I did because I needed the person I felt the worst about losing that night; I needed my best friend, and you promised you would be that for me. You told me you were okay with me moving on as soon as I was ready. I asked you repeatedly if you were sure about me bringing Adam and you said yes every single damn time! So what, Blaine? Why did you lie?"

Blaine carelessly used his sleeve to wipe his nose, too busy holding on to Kurt's every word to pay attention to the fact that he was ruining his tux. "I-I," Blaine thought hard to find the right words. "After we broke up, I really wanted you to move on because I believed I didn't deserve you anymore. I hated myself for what I did to you, and I hated the possibility that I somehow ruined you. So when you started talking about Adam, it hurt a little, but it also made me kind of glad to know that I didn't ruin you. Seeing your new found confidence made me believe that maybe I was ready to move on too, but I was wrong."

"No, you're not wrong," Kurt interrupted. "You can move on, Blaine. I promise. I didn't think I could."

"No, Kurt, let me finish. I was wrong because seeing your confidence gave me confidence of my own. It gave me the confidence to believe that maybe I can deserve you again." Blaine stared straight at Kurt, willing the love of his life to say something.

Kurt was hesitant. When he finally spoke, his voice was shaky. "Blaine, I, uh, I can't believe you."

"What?" Blaine said, hurt.

"I hear everything you're saying, and it's really sweet, but I still can't believe you."

Blaine took a step forward and reached for Kurt's hands. Kurt winced but didn't back away from Blaine's touch. "Well, I need you to know that I'm not ready to give up on you; I'm not done fighting. I'm willing to do anything for a second chance."

At that, Kurt ripped his hands from Blaine's grasp. "You lost your chance when you cheated." Blaine dropped his hands to his sides, clearly taken aback. "I've been trying to make things work with Adam, but you're making it really difficult. And I'm sorry, but I don't know if there's anything you can do to fully make it up to me, so please, if you're not going to support my relationship with Adam, just back off." Kurt stormed away, leaving Blaine pondering. He wasn't ready to back off just yet, and he really needed to show Kurt that he wasn't giving up without a fight.
