This is taking off from the episode 'The Break-Up' in season 4. Most of the dialogue in this first part is actually from the episode, I just changed it up a bit. In the original scene, Blaine denies that it was Sebastian that he was cheating on Kurt with, but in my version it actually was Sebastian. In fact, they're still seeing each other behind Kurt's back, until Kurt guessed what was going on…

I don't own Glee or any of its characters! Life would be preeeetty sweet if I did :P

Warning: Language.

Chapter 1: Prologue

"It was Sebastian. Wasn't it?" the heartbreak in Kurt's eyes was as clear as day. I really wanted to lie to him, but that would only make me feel worse.

"Yes. But it didn't mean anything; it was just a hook up, okay?"

Tears began flowing from Kurt's glasz colored eyes. "Why? Why did you do it?"

"I was by myself, I needed you. I needed you around, and you weren't there. And I was lonely, and I'm… I'm really sorry."

"You don't think that I've been lonely? You don't think that I've had temptations? But I didn't act on it because I knew what it meant. It meant something horrible and awful and…"

"I'm so sorry, Kurt. I really am." Now I was crying too.

"No, you're not, Blaine. If I meant anything to you, you wouldn't have done it. Especially not with someone like Sebastian. He almost blinded you!"

"The slushie was meant for you!" I regretted the words as soon as they came from my mouth.

"And that makes it alright does it? It's okay for him to try and throw a slushie at your own boyfriend?"

"You know what I mean, Kurt."

"Not anymore, Blaine. You mean nothing to me anymore. Have fun with your psycho fuck buddy."

Before I could stop Kurt, he was gone, running away with his hand covering his mouth in misery.

What have I done?

Just a nice short prologue to start it off :) The next chapter will be when the real story starts! Let me know if you think the story sounds good so far :)

Next Chapter: Time for Blaine to talk to Sebastian about what happened with him and Kurt!
