Story of my life

Searching for the right

But it keeps avoiding me

Isabella Garcia-Shapiro fell face down on her bed with a devastated sigh. Why, oh why could she never just be happy with what she had? Or, in this case, who she had. Isabella grimaced into her pink comforter. The day had begun just like any other in her life. Where had it gone wrong? Where had she gone wrong?

Sorrow in my soul

Cause it seems that wrong

Really loves my company

Isabella went over the day's events in her head. She had woken up at nine with a terrible foreboding in her head. Like her world was about to take a turn for the worst. She should have listened to that feeling. She had then gone over to the house across the street and immediately felt better when she saw that smile. That amazing, glorious smile on the face of the most beautiful, most amazing, most romantic boy in the world. Phineas Flynn. Her Phineas Flynn.

"Hey Phineas. Wha-cha do-in?" She had called in a cutesy imitation of the way she'd spoken when they were both ten. He had wiped the sweat from his brow and danced over to kiss her lips.

"Glad you're here Izzy." He said in his maturing voice that still had some of its boyish charm.

He's my love, my man

And this is more than love

The reason that the sky is blue

Then Ferb Fletcher had walked into the backyard. In a bathing suit.

Seven years had matured both boys, but especially the now-twenty Ferb. Muscles rippled under pale skin that seemed to capture the light just right. His longer, green hair was messy, covering his right eye. The other eye was a beautiful shade of brown, Isabella hadn't noticed this before. And now was not the time to start. At least, not with Phineas standing right in front of her.

But clouds are rolling in

Because I'm gone again

And to him I just can't be true

"Hello Isabella." Ferb's voice found her in her corner of the yard. She looked up into his beautiful brown eyes, his wet hair now brushed back across his forehead. "Phineas is looking for you, you know." He informed her innocently, though she was aware of him looking at her with an odd expression. Isabella wished she could take back her next words.

"I know." She had said. "But I don't want him to know about this."

And I know that he knows I'm unfaithful

And it kills him inside

To know that I am

Happy with some other guy

I can see him dying

Phineas knew. Isabella knew he knew. And he knew she knew he knew. Sometimes I swear that boy can hear everything I say and see everything I do. Isabella thought as she sat on her bed. But the worst part was that he didn't seem to care. She had seen the pain on his face when she had held Ferb's hand as the two walked back and knew he had probably figured out exactly what had happened behind the pool. But he had just kissed her and told her he loved her and missed her just like always.

I don't wanna do this anymore

I don't wanna be the reason why

Every time I walk out the door

I see him die a little more inside

"Where are you going Izzy?" Phineas asked as Isabella got up from the sofa. They were watching a romantic movie they both thought was way too gooey but watched anyway – they were never watching it for very long.

"Just going to get some popcorn." She said, looking at her text message.

Meet me in the kitchen – F

I don't wanna hurt him anymore

I don't wanna take away his life

I don't wanna be

A murderer

I feel it in the air

If I'm doing my hair

Preparing for another day

Isabella brushed her hair, staring at her reflection. Change was coming. Coming soon, and fast. She had to tell Phineas. Not because he didn't know – he did – but because she owed it to him to be honest about what was happening with her and Ferb.

"Are you feeling all right, Isa?" Ferb asked.

Who by the way was lying on her bed.

"You look upset about something." His concern filled her thoughts. She turned and smiled, walking over to kiss him. They kissed for a long time before she broke away.

"I have to do something. I'll be right back." She said.

"I'll be waiting, and missing you every minute." Ferb said poetically.

Where are you Iz? – Phin

A kiss upon my cheek

If I'm about to leave

Say that I might be out late

I say I won't be long

Just hanging with the girls

A lie I didn't have to tell

"Ferb?" Isabella asked. "Could you wait here for a couple minutes? I have to go help Gretchen with her baby brother." Ferb nodded, but she could see the well-disguised pain in his eyes before his mask dropped completely.

Because we both know

Where I'm about to go

And we know it very well

Isabella passed the house she'd spent almost every day of her childhood and stepped into the backyard. She climbed up the steps of the old tree house Phineas and Ferb had built when they were ten. It had stayed, unlike the other creations, and the kids continued to use it, even when they stopped pretending it was a fortress or a space ship. Even after it had been claimed by Phineas and Isabella as a secret place where they could talk without interruption about anything – but mostly kiss. Even when Isabella had violated the pact they had made to never use it for any other relationship but their own.

And I know that

He knows I'm unfaithful

And it kills him inside

To know that I am

Happy with some other guy

I can see him dying

Even as she laughed with Phineas, Ferb's pained face filled Isabella's mind. It blocked out the sounds and feelings that were usually present with the new, final realization.

They hadn't built anything since the pool party, not together.

And it was because of her. She was destroying their relationship. She was killing them. Both of them.

I don't wanna do this anymore

I don't wanna be the reason why

Every time I walk out the door

I see him die a little more inside

Ferb grimaced as Isabella looked around before coming into the house. She knew she was hurting him with the precautions, but she didn't want her friends to see her for what she was – a liar. But was her reputation worth the pain she was causing her lifetime friend and sometimes-boyfriend?

I don't wanna hurt him anymore

I don't wanna take away his life

I don't wanna be

A murderer

Our love

"Isa?" Ferb smiled. "I'm so glad you could come with me. I don't want to have to go into a date I set up alone." Isabella smiled in her blue dress.

"I'd never leave you alone." She promised, knowing all the while it was a pitiful, translucent, empty lie.

His trust

"Phineas?" Isabella asked. "Are you okay? I'm sorry, I'll never stand you up again. You can get a tracker on my phone if you want to."

"That's okay Izzy." Phineas smiled wanly. "I trust you." Isabella felt as if her heart would break in half. Because, unlike all the things she'd told him in the last month, he meant it.

I might as well take a gun and put it to his head

And get it over with

I don't wanna do this

Anymore

Ohh-whoa

"Ferb? What's the big surprise?" Isabella giggled as Ferb led her into a room, hands over her eyes.

I don't wanna do this anymore

I don't wanna be the reason why

Every time I walk out the door

I see him die a little more inside

I don't wanna hurt him anymore

I don't wanna take away his life

I don't wanna be

"Surprise!" Everyone shouted. "Happy Birthday Isabella!" Isabella gasped at all the decorations. Not elaborate, but heartfelt.

"I have a little surprise of my own." Ferb said. He twirled Isabella around so she was facing him. Then he got down on one knee. Isabella's heart thumped in her chest. Please no, I haven't made this decision yet! "Isabella Garcia-Shapiro," Ferb began "Will you marry me?" Isabella looked from his beautiful eyes to the shocked faces of her friends to the most painful face of all – the emotionless, resigned face of Phineas Flynn.

A murderer
