Disclaimer: I don't own Life With Derek, Sucks to be You by Danielle Peck, or Starbucks. If you, however, happen to own Starbucks and want to sell me rights to your Peppermint Mocha, I am open to negotiations.

A/N: Thanks for all the reviews! I love you guys and you totally make my day everytime you review. So please keep doing it!

I tried to love you baby
But I couldn't make you happy
And it just really shouldn't be so hard
I gave and you kept taking
You made some big mistakes and
You were always careless with my heart

Casey was sitting at her desk in her apartment, staring at her computer screen. Although her editorial was only half finished, she wasn't really focusing on it. Her eyes were glazed over, and a small smile played on her lips as she remembered the last two weeks.

Suddenly a message box popped up on her screen. It was from Matt. Casey rolled her eyes and glared at the monitor as if it were at fault for interrupting her daydream. He wanted to meet her for coffee. Obviously ignoring his phone calls and emails wasn't working. Casey breathed a deep sigh before agreeing to coffee that evening. She was going to explain to Matt once and for all that they were over and she never wanted to talk to him again. And then she was going to tell him if he tried to contact her again she was going to have a restraining order placed on him. There was only so much a girl could take.

That Evening

Casey walked into to Starbucks and glanced around for Matt before making her way up to the counter to order something. She smiled when she saw the Christmas decorations up – after all, that meant she could order her favorite drink. She stood in line and had just gotten called up to order when someone tapped her on the shoulder.

"Matt! You scared me!"

"Hey, sorry about that. I already got your drink – I've been waiting in the corner for you." Casey glanced to the darkened corner of the café and noticed the drinks sitting on the small, round table there.

"Okay, then. Thanks, I guess." She followed Matt to the table and sat down, picking up her drink and taking a sip. She almost grimaced when the drink hit her tongue. Of course, she thought sarcastically, I forgot Matt never remembered that I hate most coffee drinks. He never remembered that I only like mochas because lattes were more in fashion. She set down the drink, uncaring if Matt was hurt by the fact she wouldn't drink it and stared at him.

Matt cleared his throat nervously before starting. "I was just wondering if you had forgiven me yet. I mean, it was two weeks ago, and I didn't really cheat on you, and our relationship should mean more to you than this, and I think we could move past this and right back into our relationship. After all, I love you, you know that." His verbal puke sat there in the air around them as Casey inwardly groaned. She had to admit that she had expected this, but some small part of her had hoped that the only reason Matt had contacted her was to apologize and say he was going to back off.

"First of all, our relationship didn't mean enough to you to prevent you from cheating, which you really did. Second of all, our relationship was crap. Most of the time I sat at home waiting for you to call and make last-minute plans, and I hated that about myself. Thirdly, there is no fucking way you loved me. No way. You don't cheat on people you love, because love means you put the other person above your own wants and needs. And finally," she took a deep breath before plunging into the part of the argument that was going to drive Matt insane.

I'm happier now
Ain't it funny how
All it took was leaving you
To finally feel good again
You say you're sorry now
That you figured out
Just what it was that you had to lose
It sucks to be you

"I am so much happier since I broke up with you. I enjoy my job again. I've been out with my girlfriends because I am not waiting at home on the off chance you'll call. And my new boyfriend is considerate and acts like I actually mean more to him than the dirt scrapped off the bottom of his shoe. So I'm sorry that you finally realized that I'm amazing and you want me back, but you are just not going to get that chance. Two weeks ago, I would have given it to you. But the minute you put your lips on hers, we were over. Forever."

Casey stood up and put her coat back on. Matt sat there looking stunned until she starting putting her scarf on, and then he seemed to realize what was happening and grabbed her arm to stop her. Casey glowered at his hand until he removed it, feeling oddly like his fingers had been burned.

"Case, c'mon, you know I'm sorry for all of it. And you know you want me back. Just admit it. This is the last chance I am going to give you."

Casey's expression was priceless. It was as if she had just put a rotten and moldy piece of bread into her mouth. "I cannot believe I went out with you for sixteen months! You are an ignorant, arrogant, obnoxious, selfish, and inconsiderate ass!"

As she spun around to leave, Matt got up and grabbed her arm. And then a voice stopped him in his tracks.

You used your last chance
so I went and found romance
so you really just can't stand it, can you?
You see the smile on my face
and it really drives you crazy
Just to see how much better off I am with out you

Casey and Matt both spun around, Matt automatically dropping his hand and Casey beaming. "Derek!" she murmured, relieved. Ignoring Matt's furious expression, she went straight into the arms of the brunette who had commanded Matt to let her go.

Derek's arms went around Casey and he gave her a quick squeeze while glaring at Matt. "I hope that wasn't you trying to stop my girl from leaving, Hunter," he drawled. "'Cause you know if it was, I'm going to have to punch you. And then you'll probably have to punch me back, and we'll get into a fight, I'll totally humiliate you and your evening will be totally ruined. And I'm sure you don't want that, do you," he threatened.

Matt looked like he was going to protest the total humiliation comment, and then he looked at Derek's 6'2", hockey player frame and swallowed back any retort. "Yeah, whatever," he said sullenly before looking at Casey, who was smiling up at Derek, whose arm was still slung around her shoulders. "I'll talk to you later, Case."

Casey looked at him, having forgotten for a moment that he was even there. "No, you won't, Matt. If you try to contact me again, I'm getting a restraining order. I am sick to death of belaboring this point over and over. We are over!"

I'm happier now
Ain't it funny how
All it took was leaving you
to finally feel good again
You say you're sorry now
That you figured out
Just what it was that you had to lose
Well it sucks to be you

Derek turned Casey and they both started walking out to the car. Matt followed, whining at Casey. "C'mon Case, I get it. I was stupid, I was an idiot, and I should have treated you better. You deserved better and I promise I'll do better. Just give me another chance!"

Derek turned around. "What part of we're over don't you get, dude? She doesn't want to see you or talk to you, so I don't want to see you around her again. I don't want to hear that you called her, that you emailed her, that you accidentally drove by her apartment complex. If you bother her again, she won't have to worry about getting a restraining order, because I will kill you."

Matt looked pleadingly at Casey. "C'mon Case, you aren't going to let him threaten me, are you?"

Don't worry baby I'm sure you'll find someone too
Yeah who'd put up with you

I'm happier now
Ain't it funny how
All it took was leaving you
to finally feel good
You say you're sorry now
That you figured out
just what it was that you had to lose

Derek growled and Casey almost screamed. "I could care less whether he threatens you or not, Matt. I don't care about you. I don't even hate you, because hate would require me to feel some emotion for you, and I don't. Derek could beat you up and I wouldn't shed a tear. In fact, I'm thinking about asking him to anyways. We're done. Maybe if you stop bothering me you'll find someone new, someone who won't care if you are an inconsiderate, cheating slob, but I doubt it. It doesn't matter to me. Just leave me alone!"

Matt looked at her. "We're really over?"

"Yes, Matt, we're really over."

Matt looked at Casey for a few moments longer, and then turned and walked away silently. Derek looked down at Casey, who had a relieved expression on her face. "I think he finally got it, Derek," she said softly.

Derek laughed and squeezed her. "Took the idiot long enough. C'mon, let me take you to dinner, babe."

Casey smiled at him. "Sounds good to me. That coffee he bought me was disgusting and I need something to get the taste out of my mouth." They laughed and walked to Derek's car, leaving Casey's to be picked up later…much, much later.

A/N: So Matt, the idiot, has finally realized that he and Casey are over and will henceforth be absent from this story. Yay! All Dasey all the time now! Yay!
