"Before our duet, we're gonna do it….."

Artie knew it was wrong. He was cheating on Quinn with Brittany. It was duet week, and of course Artie wanted to sing a duet with Quinn. But, Beth was sick, and Quinn had been out all week. So he was just going to just do a duet with Brittany, who didn't have a partner. Brittany was hot and all, but he was with Quinn.

"You're on the football team now anyways. So, we were gonna get around to this at some point" Brittany said.

Artie couldn't believe it. Was he about to lose the big V?

His mind was in another place when Brittany kissed him.

This was it….

Beth was a lot better by Friday.

Thank god.

Quinn entered the school with a smile on her face. She was back as head cheerleader, Beth was healthy, and she had an amazing boyfriend she hadn't seen all week.

"Hey Quinny" Santana stepped in front of her

"What do you want Santana" Quinn snapped

"Umm, how can I say this without being a bitch? Oh who cares, I'm always a bitch. Artie cheated on you. With Brittany."

Quinn couldn't breathe.

"You're lying"

Santana pulled out her phone, and showed Quinn the text message

Hey San!,

OH MY GOSH, YOU WON'T BELIEVE THIS! I HAD SEX WITH ARTIE!

A tear ran down Quinn's face.

She pushed past Santana, and ran down the hallway to the library.

Of course, Artie was there.

"YOU CHEATED ON ME!" she yelled

"Who told you?"

"THAT DOSEN'T MATTER! AFTER EVERYTHING WE'VE BEEN THROUGH! I THOUGHT YOU LOVED ME!" everyone in the library was staring at them

"Quinn…I-"

"SAVE IT! WE'RE DONE!" she yelled, and stormed out of the library.
