Disclaimer: I don't own Glee, or the song 'It's not right, but it's ok' All I own is the alternate ending.

A/N: So, after watching the Whitney Houston episode I just knew I had to make a oneshot. Here's how it would've gone had I been writing it.

"This song is for anyone that's ever been cheated on."

"This is insane, I didn't cheat on you."

Everyone turned to stare at Kurt, shocked at what was being implied. Kurt tried his best to ignore his friends as they stared shamelessly. His face showing no emotion as he watched his boyfriend started to sing.

Friday night you and your boys went out to eat, ohhhh.

More heads turned in his direction, but this time Kurt didn't have pretend not to notice, he was too busy staring at his boyfriend, who had the gall to sing this song to him.

Then they hung out, but you came home around three, yes you did.

Blaine actually looked at him as he said that line. Kurt couldn't believe Blaine was doing this. Santana and the others were looking at him, still shocked, but somewhat accusingly. This pissed Kurt even more, Blaine was dragging this personal affair into the glee club, and now it seems he was turning his own friends against him.

If six of y'all went out, then four of you were really cheap,

cause only two of you had dinner, I found your credit card receipt.

'No, you looked through my phone.' Kurt thought angrily, fighting the urge to throw said phone at Blaine.

It's not right, but it's O.K.

I'm gonna make it anyway.

Pack your bags up and leave,

Don't you dare come running back to me.

Everyone was singing with him, Kurt idly noticed, holding back the tears of sadness and anger at the cruel words Blaine had practically spat at him.

It's not right, but it's O.k.

I'm gonna make it anyway.

Close the door behind you, leave your key.

I'd rather be alone than unhappy.

Kurt stared ahead, trying, to ignore the stinging in his eyes, his hands clenched to stop the shaking. 'Fine... Fine. If that's what he wants.' Kurt thought spitefully.

I've been through all this before.

'Yes you have, only that time you were the one cheating on me.' Kurt retorted in his mind, not having the voice to say it.

Don't you turn around,

There's no more tears left here for you to see.

'Clearly.' Kurt thought, choking silently on unshed-ed tears, feeling incredibly alone and worthless at the thought that someone he loved so much could stop loving him so quick.

Was it really worth you going out like that?

Tell me.

Then the whole club sang, faces passionate, and maybe Kurt was imagining it, but some looked mad, like the hated him, and want him to leave too. Just like Blaine did.

You were making a fool of me.

Kurt forgot everything, he forgot that he was sad, that he was, in the choir room, that Blaine was still singing, that he was suppose to be holding back his tears. He just knew one thing, that he was angry. He was angry at Blaine, and his glee club, and himself, but mostly, he was angry at Blaine, for over reacting, for humiliating him, for turning his friends against him, for being a hypocrite, for making him feel worthless. He was angry at Blaine, for everything.

So he stood up, he stood up so fast his chair fell backwards. He marched up to Blaine, who had turn to him in shock and had stopped singing.

SLAAAP!

Blaine held his cheek numbly, before coming back to reality and glaring at Kurt.

"What is your problem?" He asked angrily.

"What's my problem? What's my problem? Really, you wanna know?" Kurt hissed at Blaine, who suddenly noticed the steady flow of tears down Kurt's face.

"My problem is YOU. You shameless, insensitive, hypocritical prick. You're making such a fuss about me texting this guy, who didn't even know that I was taken, and has backed off since I told him. You called it cheating, but you had been grinding, and practically dry humping Smythe in the past, who knows your taken and still constantly pursues you.

You texted him often, without my knowledge, because I don't care who you text because that's your business. You called each other, you talked, he flirted and you always went along with it. You tried to have sex with me in the back of my car after spending the whole night rubbing up against strangers, and even worse, Smythe. Although I forgave you for that, I don't care about it because you said you loved me.

That's all that matters to me. That at the end of the day, I'm the one you love the most. But I guess you don't love me as much as I thought, since you're so willing to throw it all away because of some texts, when I've loved you since I met you. Since you took my hand in that hallway my love has never strayed. I watched, and helped, you serenade Jeremy, make out with rachel, flirt with practically everyone before you even started noticing me.

Can't you see Blaine, you're out of my league, you're better looking, and more charming and I'm constantly afraid you'll leave me for someone better, because I can't possibly be enough for you. Then Chandler started telling me how great I was, and I couldn't help but feel better, because If Chandler could see some good in me, if he saw something likeable about me, then maybe there is a reasonable explanation as to how I ended up with you.

But If I make you soo unhappy, then maybe I should leave, because being with you is just setting myself up for heartbreak, because I would give you everything, and I'm not sure you'd do the same. Maybe I was making a fool out of you, you're a fool for giving me a chance, and I'm a fool for believing we had one." Kurt told Blaine, chest heaving, his hands were shaking.

Blaine stared at him in shock.

"Kurt...I.." Blaine tried to say when Kurt cut him off.

"Don't. just...don't. I don't want to hear it." Kurt's voice was quiet and cracking.

Kurt went to his seat, picked up his bag and walked away.

Things were not right, and Kurt was never gonna be O.K.
