Disclaimer: I don't own House, M.D. Or "Used To" by Daughtry.

A/N: This is from Cameron's POV, after House has broken up with her…R&R please. OOC sometimes, but that's the way it goes. No flames please. AU.

HOUSEHOUSEHOUSE

Allison curled her legs up underneath her and cried. Just…cried. She missed him. She missed him so much. Everything about him had been everything she wanted and needed. She looked out the window, and wondered if right now he was looking out a window in his own apartment and thinking about her.

You used to talk to me like
I was the only one around.
You used to lean on me like
The only other choice was falling down.

He was wrapped up in her. She could see it in his eyes, in the way he tilted his head when she talked, the way he smiled when she laughed, the way he held her when she cried.

He would talk to her about anything, and when they were together…he would talk to her like nobody else was there. In the office, differential diagnoses had been known to be discussed just between the two of them, while an angry Chase and a disgusted Foreman just sat there.

Then there was the time she got the news from home that her dad was sick. He had leukemia. She'd taken the phone call, promised her mom she'd be on a flight out ASAP, wiped her eyes, and returned to the office.

"So nice of you to join us," House sneered, mainly for show for the other two, but then he saw the look on her face. "Something wrong, Cameron?"

The boys ignored it and Chase said, "Could be epilepsy or a seizure disorder."

House, on the other hand, got up and moved towards her. "Allison, what's the matter?" he tilted her chin up with his fingers and saw her pretty brown eyes filled with tears. "Are you ok?" he hugged her close to him. She cried on his shoulder, and he talked her through it, all while Chase and Foreman continued the differential.

You used to walk with me like
We had nowhere we needed to go,
Nice and slow, to no place in particular.

And those times they had walked in the park, or down the street, or even in the hospital corridors. He would walk next to her, and she would be on his left side, the side without the cane. And they walked slowly, as if it didn't matter, as if nothing mattered.

Her hand would wander up to his, and she'd tuck her small fingers in between his larger ones, and squeeze tightly. And he would squeeze back. She knew that things were…changing, when he didn't squeeze back.

Chorus: We used to have this figured out;
We used to breathe without a doubt.
When nights were clear, you were the first star that I'd see.

They did used to have everything figured out. They knew they both loved each other. They both knew that that was what mattered. She knew that he wasn't as…sure of their future as he was. She also knew that he didn't like to think about those kinds of things, so she didn't press it.

She used to wake up…happy in the mornings. She was absolutely sure he did, too. The knowledge that in a few hours she would see the man she loved would fill her with happiness. The fact that they both knew what they were doing and that they belonged together, at least at the moment, let her breathe easier than she had in a long time.

She was wrong.

Chorus: We used to have this under control.
We never thought.
We used to know.
At least there's you, and at least there's me.
Can we get this back?
Can we get this back to how it used to be?

"Oh, no. Oh, please, Greg, no." she'd begged. "No. Don't say it, Greg. If you're going to say what I think you are...just don't. I love you. You love me. Isn't that what matters?"

But it didn't matter. At least not to him. She wanted him back. She wanted the happiness, the sheer happiness that came from knowing she was with him. It was true: she hadn't ever thought about whether the two of them together was right or not. She'd known. She'd known it was. Why had he screwed it up? She questioned now, crying. Why?

I used to reach for you when
I got lost along the way.
I used to listen.
You always had just the right thing to say.

Whenever things got rough, or hard, he had been the person she went to. When she was tired, or angry, or sad, he was the ever understanding person. He always had the exactly perfect thing to say to make any horrible situation better.

He'd proved to her that he could change. He was still the snarky, angry, misanthropic man she and everyone else knew (and, ok, loved). But he had changed when it came to being able to care about another person. Until he'd also proved that he couldn't stay the same forever.

I used to follow you.
Never really cared where we would go,
Fast or slow, to anywhere at all.

She never cared where they would go, what they would do, or who they would see. She never cared about the bad qualities in him, because she was too wrapped up in the good ones. She let him make decisions, and never cared about what they were. He had been enough. Boy, was that ever stupid, she thought to herself now.

"House…Greg…" she cried, spitting out his name in a combination of anger, fear, and sadness. "I miss you!" Tears came at an alarmingly fast rate, and she pounded her leg with her fist. "What did I do wrong, huh? Please, tell me, what did I do wrong?"

She heard a knock on the door. She quickly dried her tears with her hands and opened the door, sniffing.

"Allison. You did absolutely nothing wrong. I am so sorry. So sorry. I'm stupid." Gregory House wrapped his arms around Allison and hugged her tight, kissing the top of her head and whispering in her ear things she couldn't hear over the pounding of her heart and her brain telling her that it couldn't possibly be true.

But it was.

Chorus

I look around me,
And I want you to be there
'Cause I miss the things that we shared.
Look around you.
It's empty, and you're sad
'Cause you miss the love that we had.

Chorus

"Oh, you're here. You're here." He nodded and they sat down on the couch together. She laid her head on his shoulder and smelled his shirt. He smelled…good. Clean. He smelled like, well, to her, he smelled like security. Like the person she could, and would, be with forever. "You're not going anywhere, are you?"

"Nope. Not anymore." He kissed her, on the lips this time, and said, "I promise."

A/N: So, this one was a fair bit happier. R&R:)
