By the time bio 101 came around that Monday Arizona and Callie hadn't seen each other, talked, or texted. After spending everyday together for months, a couple days without interaction felt like an eternity. They both wanted to see each other, but secretly hoped the other wouldn't show up to class, not knowing how to act, not trusting themselves to stay back and give the other her needed space. Callie was already in her seat when Arizona walked in, and when Arizona saw her she almost turned back and walked out, but pushed on instead. She went to take her seat and Callie kept her eyes down not wanting Arizona to see that her eyes were still puffy and swollen from her weekend of tear, which she even woke up to this morning. Arizona knew. She hated that Callie was so upset, but she didn't blame herself. She knew she did the right thing for Callie, even if she was hurt right now. Pushing Callie away when all she really wanted to do was push her back against that sink and kiss her was one of the hardest things she's ever done. So, yes, seeing that Callie was so upset that even her physical appearance gave it away, hurt. She literally felt an aching in her chest, but it was what Callie really needed her to do. Callie wasn't a cheater and if she cheated on Cameron with Arizona she would never be able to face either of them again, much less herself.

Between lab and lecture, they were in for four and a half hours together. They tried to avoid all contact, but being lab partners made that quite the challenge. One would softly ask the other to pass her something or what page they found something on, but they never made eye contact. They would gaze at each other when the one was looking in the microscope or had her back turned, any time there was no chance of getting caught. The time passed painfully slowly, but eventually it got to the end of class. Callie walked out first in a hurry to get back to the safety of her own room. Arizona let out a deep breath and waited a minute to get some space between Callie and herself. She stopped short when she saw Callie right outside of the door. Cameron stood in front of Callie with one hand on her shoulder, the other pushing her bangs back gently. Arizona's body betrayed her and let out a sharp exhale that almost sounded like a laugh. Callie turned her head away from Cameron and they made eye contact for the first time. Arizona just shrugged her shoulders the slightest bit and gave her a sad, weak, half smile as she walked past them both and out of the building. The moment was quick enough for Cameron not to notice and Callie turned back to face him, realizing he had said something.

"What?"

"I said my professor had to cancel class because of a family emergency. You said you wanted to talk, so I asked if you wanted to get something to eat."

"Oh, sorry. Yeah we should talk, but let's just go back to your room."

"Is this about whatever happened between you and Arizona this weekend? You kept saying you needed space and I backed off, but I've never seen you so upset. I want you to talk to me about what's going on with you. We used to talk about everything."

They went into his room and Cameron sat near the head of the bed. Callie closed the door behind her and sat towards the end of the bed, distancing herself and leaving her closer to the door.

"This isn't about Arizona and me. This isn't even about you and me. Not really."

Cameron looked lost immediately. His brows furrowed and he scooted closer, taking her hand.

"What do you mean? Are you okay?"

Callie let out a shaky breath and took a minute to think.

"On the football team, you're a receiver right?"

"Yeah, but what does that-"

"And you've been in that position since high school right? Maybe even junior high or on a little league team?"

"Yeah, ever since I was a kid." This time he didn't interrupt.

"Now imagine your coach suggested you try out being running back or linebacker. You don't want to try playing a different position. You're comfortable in yours, you know it, you like it, but you think about it. You think, 'maybe I won't go straight to playing linebacker because that's completely different, but maybe I'll play running back for a little while.'"

Cameron nudged a little closer.

"Callie calm down. Slow down. You always do this when you're nervous. You're not making any sense baby."

Callie let go of his hand and pulled back at the term of affection, realizing he wasn't getting it.

"Cal, just tell me what this is about."

She didn't want to hurt him. They had been together for so long and had been through so much together. She didn't know how or when it happened, but she realized she didn't love him anymore, not in the same way.

"This isn't working anymore Cam. We don't work anymore."

Before her very eyes flashed the five stages of grief.

Denial. "No, we're fine. We're great! Same as ever and so happy too. You don't mean that, you're just having a bad day because you're fighting with Arizona, that's all this is. We'll be fine again tomorrow."

"Cameron I'm sorry, but we can't keep going like this. It wouldn't be fair to either of us to stay in a relationship we're not wholly in. You had to see this coming, we barely talk anymore."

Anger. "Because you never talk to me! Ever since school started and you met Arizona you haven't been the same!" He was pacing the room, yelling, but suddenly stopped, realization hitting him. "You're gay?" He phrased it as a question, but it was a flat statement. "Oh my god, did our relationship mean nothing? You just used me and now you're leaving me for Arizona!"

"I don't know what I am, but our relationship didn't mean nothing and you know it. You were my first love Cam, I'll always love you. This isn't about Arizona, this is about me. Cameron I didn't look for this or expect it to happen and I still love you, it's just not the same anymore."

Bargaining. "We can still be together. We'll work through this and everything will be fine. We can have threesomes sometimes if you want. Yeah, that's it. We can make that work. Every guy's dream right?"

"No Cameron. Neither of us would be happy with that."

Depression. "I don't think I can live without you Cal. You were there when my parents split up. You helped me get into college. You helped me grow up, take on responsibility, become a good man. I can't live without that."

"It'll be hard for both of us. I wanted to be with you forever. We made it through a lot together, but I didn't make you a good man. You did that yourself. You did it all, I was just lucky enough to be a small part of it. We can still talk, maybe not at first, but if you ever need me I'll be there."

And finally, Acceptance. "I'm going to miss you so much. I love you."

"I know. Me too."

He sat back down defeated. "So what now?"

Callie stood up. "I'm gunna go and we're going to start to learn how to live without each other." She back towards the door and had her hand on the door knob. "We'll see each other around." She gave him a forced half smile and he gave her one back. She turned around and left.

"Tell me again."

"Arizona I've already told you fifty times already, in the last hour alone."

"Teddy. I need you to tell me again." Arizona's eyes were pleading with her.

"You did the right thing. Callie is with Cameron. It would've been wrong. She needs to figure it out. You would just get hurt. You can't put yourself in that situation again."

Arizona let out a deep breath then a couple more through her open mouth.

"Okay."

"You really did do the best thing for both of you. You're not the kind of person who can sit by and be a dirty mistress. That's just not who you are. And Callie's not the kind of person to cheat and have a dirty mistress. It would have killed you both."

"I wanted her for so long. I got myself to stop wanting her and thinking about her like that, and then she wanted me. She wanted me in the way I wanted her for so long and it could've been perfect."

"I know."

"I had actually thought I didn't feel that way about her anymore. I had thought I'd been over her, and then in that bathroom when I heard that it was a possibility- I've been kidding myself this whole time."

"I know."

"She told me how she felt and I just yelled at her. I accused her of being a homophobe. She just made this huge realization and opened up to me and I yelled at her and walked out."

"You handled it the way you needed to to be able to deal with it. A little extreme, but you've never been able to deal with your emotions."

"Hey, I-"

"You don't Arizona. You pretend that nothing happened and you move on and maybe you feelings lessen in time, but they never just go away. It's better that Callie knows that early on anyway, so maybe this will help in the long run."

"There is no long run Teddy. I told her to stay in her 'perfect world' and leave me out of it, and I told her to figure herself out on her own. I walked away, after being a raging bitch, and she's still with Cameron."

"It has only been a couple days, you don't know that."

"They were together today. He had his hands on her."

"Okay, but that doesn't mean-"

"It doesn't matter Teddy. Even if she and Cameron weren't together I don't see how she could just forgive me for talking to her like that."

"You could try to talking to her."

"Since when do you even like Callie? When we first became friends you didn't want me anywhere near her."

"Hey, I like Callie I just didn't want you to get hurt."

"That didn't pan out too well."

"Just give it a couple days. You'll see her in class. Maybe you can try to get back to a decent place where you guys can talk a little. We've been friends since we were kids and I've never seen you with anyone like you were with Callie."

"I don't want to talk about her anymore. I just want this semester to be over already."

"You should call Tim. I don't know how, but he always knows just what to do."

"I called him before. He's going to come and stay over this weekend."

"Really?"

"He's coming to spend time with his sister, not hookup with his sister's best friend."

"We'll see about that."

"And suddenly I'm dreading this weekend even more."
