Kurt wouldn't even let himself wonder if it was true. There was no way. Hayden would never do that.

Then again, a few months ago, Kurt thought he would never cheat on anyone either…

Rachel knocking on his door snapped Kurt out of his thoughts, and he was quickly reminded that he had answered his phone in the middle of a conversation and when he heard Blaine, he had ran to his room and shut the door. "Kurt, is everything okay?" She asked softly, knocking again.

He sighed, running his hand through his hair quickly, "Yeah, come in."

Rachel walked in his room and joined him on his bed. "Who was that and why did you run in here?" She asked jokingly. When Kurt just looked at her, her eyes widened, "Kurt, who was on the phone?"

"Blaine," He said softly.

"No way," Rachel said, trying not to act too excited. She couldn't deny that she was definitely a little happy that Blaine had called. When she saw the upset look on his face, though, her smile fell. "What's wrong?"

"He's just being stupid," Kurt replied, trying to blow it off, though he knew it was useless.

"Kurt, what did he do?" She pushed.

He sighed, "It's nothing, really. He's just trying to upset me because he's jealous or angry or something…" When she raised an eyebrow, he clarified, "He tried telling me that Hayden is cheating on me."

"And what made him think that?" Rachel asked calmly.

"Oh God, you think he's telling the truth!" Kurt exclaimed at her response.

She shook her head quickly, "I didn't say that. I just asked."

Kurt studied her face for a moment before answering her, "Apparently, he saw him kissing another guy."

"Oh really?" Rachel asked, trying to stay calm for Kurt's sake. He obviously didn't believe Blaine, and she didn't want him thinking that she did.

He shrugged, "I don't believe it. I think he's just upset that we haven't talked."

Rachel planned her next words carefully before speaking. "That doesn't really sound like him…"

"Excuse me?" Kurt asked, eyeing her.

She shrugged, "I'm just saying… He's never seemed like a manipulative person. Why would he start now? He's always been so laid back…"

"Like I said, he's mad or jealous or something… Hayden would never." When Rachel was just quiet, he spoke up again, "You think he would cheat on me?"

"I didn't say that," Rachel replied carefully.

"But you're thinking it," Kurt said, "I can tell. Why do you think Hayden would ever cheat on me?" Though he didn't want to believe it, Rachel's responses were worrying him.

She sighed, "I don't know… Maybe for revenge? You know… because of what happened with you and Blaine…"

"Are you kidding me?" He exclaimed.

"I'm not saying that Blaine is right," She said, trying to save herself, "I just don't want you do rule it out just because you don't want to believe it."

"Can you please leave my room?" Kurt asked numbly, and Rachel got up wordlessly and shut the door behind her.

For the next couple of days, Kurt tried to act normal when he hung out with Rachel and Hayden. He and Rachel hadn't talked things out after he had gotten upset with her, and they probably wouldn't. It wasn't that Kurt didn't want to discuss things and have an adult conversation with Rachel, it was just that he really didn't even want to consider the fact that Hayden could actually be cheating on him.

Kurt knew how broken up and upset Hayden had been when he had told him about Blaine, and he couldn't imagine him doing something like that. Not to mention, Hayden hadn't done anything to make him suspicious. In fact, if it weren't for Blaine saying something, Kurt would have never even thought about it, which meant nothing could be going on.

Even when the three of them hung out after class, Hayden seemed fine. If Blaine had really seen him with another guy, like he had said, Kurt figured he would at least be acting strange. But everything was fine on both Wednesday and Thursday when they hung out. He and Hayden even went out to dinner to one of Kurt's favorite restaurants on Thursday night.

Though Kurt was certain that everything was fine between them, he found himself over thinking little things that Hayden would say while they were out to dinner and he had to stop himself. He had never been jealous or suspicious of him before, and he wasn't going to start now, just because Blaine was trying to be manipulative.

"How are your rehearsals going?" Kurt asked, taking a sip of his water as they waited for their food. Hayden had been really busy recently with school, and they hadn't had a nice night to themselves for a while.

"Huh?" He asked, glancing up from his phone before he set it back on the table, "Oh, they're going good. I'm just glad I had some time to spend with you." Hayden smiled and reached forward to take Kurt's hands.

Kurt smiled back, "Yeah, I am too."

Hayden then glanced around for their waitress before standing, "I'm going to run to the restroom before our food gets here." Kurt nodded in response as he walked away. As he waited, Kurt glanced down at where Hayden had been sitting and noticed that his phone was still sitting where he had left it on his table.

He had never been the type of person to get jealous or suspicious, and it was probably just Blaine getting into his head, but a small voice told him to grab the phone and look through his texts. Kurt tried to convince himself not to. There was no way Hayden was cheating on him. He wasn't going to find any suspicious texts. He was freaking himself out over nothing. Besides, if he had something to hide, he wouldn't have left his phone sitting out.

What can it hurt? If he's really not hiding anything, then there's no harm in looking… You won't find anything bad…

The voice in the back of his head was persistent and before he knew what he was doing, Kurt was picking up his phone and going to the most recent text messages. He glanced around before scrolling through them quickly. They were from someone named Alex. Kurt had heard the name before, and was sure it was one of Hayden's friends from class.

As he scrolled through, he saw that most of the texts were about class or rehearsal and he wanted to kick himself for being suspicious. Then there was one that he stopped at, which read "Had fun hanging out today."

It was only from a couple of days ago, and as Kurt tried to figure out exactly which day it was, he noticed Hayden heading back from the bathroom and quickly returned the phone to its spot, making sure he had closed out of the conversation. The little voice in the back of his head tried to tell him that the text was suspicious, but he tried to push it away as Hayden sat back down in front of him, his cheerful happy self.

As they ate, Kurt wondered if Hayden would cheat on him to get back at him for what had happened with Blaine. Of course, now that he had read his texts, he was even more paranoid, even though he hadn't even found anything substantial.

"Babe?" Kurt asked softly, putting down his fork and looking at his boyfriend.

Hayden glanced up at him and smiled, "Yes?"

"Are we okay?"

Hayden's brows furrowed as he looked at him, confused, "Of course we are. Why wouldn't we be?"

Kurt sighed, "Well, we just haven't really talked about… you know, what happened between me and Blaine since that night, and I just wanted to know that we're okay…"

Hayden watched him carefully for a moment before reaching forward again to take Kurt's hands again, "We're fine. Don't worry about it. It's in the past, okay?"

Kurt nodded, "Okay."

Though Hayden's words should have been comforting, Blaine must have gotten in his head, because over the next couple of days Kurt couldn't stop thinking about things. Hayden still hadn't given him any reason to be worried, but he couldn't help it. When Kurt asked Rachel what he should do about it, she suggested that the two of them go out over the weekend. She told him not to worry about it too much, but to watch for anything suspicious while they were together. Basically, it was what he was already doing.

He had asked Hayden if he wanted to hang out on Saturday, though – maybe see a movie and have dinner, then spend the night together. Hayden had originally been busy, but he eventually pulled some strings and agreed that a date night was in order.

Saturday afternoon, Kurt was getting ready to head to Hayden's house while Rachel sat in the living room working on homework. He and Hayden were supposed to meet up around five and go to a movie, then dinner, then go back to Hayden's place and hang out. Kurt couldn't help but be excited, despite the little voice in the back of his head telling him to be on the lookout for anything suspicious. He never got to spend the night at Hayden's anymore and he was missing it.

Around four, Kurt tried calling his boyfriend and got his voicemail. "Maybe he's still working on school stuff," Rachel suggested, "After all, he did say that he had to pull some strings so he wouldn't be busy all night."

Kurt shrugged it off and agreed with Rachel. They still had an hour before they were supposed to meet up, anyway. When he tried calling again fifteen minutes before five though, he got his voicemail again. Kurt sat down on the couch with Rachel and turned on the TV, waiting to hear back from his boyfriend.

"Don't stress about it," Rachel said, not looking up from her work, "You have all night to hang out with him."

Kurt nodded, "Yeah, yeah. I know."

"You're not worrying about things, are you?"

Kurt shrugged in response, trying to avoid talking to Rachel about things. He didn't want another lecture from her about how Blaine might be right. "Look," She started, seemingly reading his mind, "I know I upset you the other day when I said that he would cheat on you… Just don't let it get into your mind. I wasn't thinking when I said it, and I don't want it to make you over think things, okay? I'm sure you guys are fine."

Kurt smiled at her reassuring words, "Thanks, Rachel."

By six-thirty, though, Kurt was pacing back and forth in their apartment, bored. He had been ready for over two hours and just wanted to get out of the house.

"Maybe he's getting ready," Rachel offered when Kurt tried calling him again and didn't get an answer, "Why don't you just go over there?"

Kurt sighed, "I guess I have nothing better to do." He threw his shoes on and opened the door to leave, "I'll talk to you later." Rachel nodded in response, and at that, he was out the door. As he walked, he sent a text to Hayden, letting him know that he was on his way. He tried not to get worried about why he wasn't answering his phone because he figured it wasn't a big deal. They had planned going out. There was no way he had forgotten about it.

When he reached Hayden's door, Kurt knocked softly a couple of times and waited for him to answer. When he didn't right away, he started to get a little worried. He couldn't help it. Hayden almost always answered his phone. And now that he wasn't answering his door either, Kurt started to wonder where he could be.

Without thinking about it, he tried the doorknob and found that it was unlocked. He let himself inside, reminding himself that he had done it a million times and that Hayden wouldn't think it was weird if he did it again. As he made his way down the hallway, he told himself that Hayden was probably just getting ready and couldn't hear him. He headed to his boyfriend's bedroom and adjoining bathroom, and noticed that the bedroom door was closed.

Of course. He's just getting ready. Stop freaking out.

When he got to the door, though, he swore he heard a small gasp from on the other side and he paused before he opened it. He waited for a moment, and there it was again. Hayden was definitely in there but it almost sounded like there was someone else there too...

Kurt tried to stop his heart from sinking as he grabbed the doorknob and twisted, praying that he was just being paranoid.

When he saw what was on the other side of the door, though, he wished he had never opened it.

Hayden was in there, as he suspected, but so was someone else. They were both naked, from what he could see, though they were mostly covered by a blanket (thankfully). Blanket or no blanket, though, Kurt could assume what was going on. His hand immediately flew to his mouth when he gasped and he started to back away, already feeling tears forming in his eyes.

Hayden and the unnamed guy had heard the door open, and had stopped moving when they saw Kurt. When Hayden started to get off of the bed, Kurt turned to run out of the room.

Blaine was right. He was right all along, and you didn't believe him.

He could hear Hayden calling his name behind him, but his legs kept carrying him down the hallway and toward the front door. As he ran, he heard the other guy say something about how he was supposed to call before he showed up.

Great. So they were trying to get a quick fuck in before your date.

Kurt threw the front door open and stormed out, determined to get as far away as possible from Hayden. He was stopped short, though, when a hand wrapped tightly around his wrist, spinning him around. Hayden was standing just inside the door in his boxers, eyes wide like a deer in the headlights.

"Let me go, Hayden," Kurt said, voice stern.

He held tight, though, "Kurt please, listen to me."

Kurt scoffed, "What can you possibly say that is going to make things alright?" When he was quiet, Kurt continued, "I just walked in on you fucking someone. Let me go."

Hayden didn't let go, though, "Please listen."

"How long?" Kurt asked instead. He really wanted to be as far away as possible, but since Hayden was holding onto him, he asked, "How long has this been going on?"

Hayden glanced back behind him, toward the bedroom before clearing his throat and quietly saying, "A while."

As if he couldn't feel any worse, his heart sunk even more, "How long?"

"About six months," Hayden answered quietly, looking down.

At that, Kurt ripped his arm from Hayden's grasp, "Goodbye, Hayden."

He had started to walk away when Hayden called after him, "Isn't this a little hypocritical of you, Kurt? You cheated on me too!"

Kurt then turned on his heel and stormed back to him. "Don't even try to compare this to that. I kissed him. Once. And I felt bad and told you. You've been hiding this shit from me for months!" He yelled, his face inches from Hayden's

"Oh don't tell me you wouldn't have fucked Blaine if you had gotten the chance," Hayden spat.

Without thinking, Kurt smacked him in the face, then turned to walk away again without another word. He could hear Hayden yelling obscenities after him and calling him names but he kept walking without looking back and tried not to cry any more than he already had because Blaine was right all along.

Blaine was right.
