(A/N I got hit with inspiration so here is an actual ending to this previous one-shot)

Phineas sat, silent, shocked, on his end. He was amazed there was an answer at all.

"Phineas?" Isabella asked again snapping Phineas out of his shock

"Isabella!" He let out her name with a sigh of relief "It's so good to hear your voice."

"What do you want Phineas?" Again Phineas was snapped even farther into reality. Isabella didn't want to hear his voice. She was mad at him.

"Umm.. Well... I just called... to.."

"What? To explain yourself?" Phineas smiled a bit

"Yea that's it."

"Go ahead then." His smile died as quickly as it arrived.

"I.. cheated on you." He said defeated. Isabella laughed lightly on the other end

"Most people would have started with something a little less honest." Phineas smiled glad to hear her not hang up

"Well I've never been 'most people'. Its just.. I don't know. Things got out of control and before I knew it something was happening. And then when I knew I had to break it off, which I did, it was too late. And.. I wish I could come up with something better than this.. I'm sorry. I know its not enough and I know it never could be. I just.. I don't know.. You deserve better than someone who can't even recognize that he had the best thing in the world until... I'm just going to go."

"The Phineas I know would never give up like that." Isabella said it with all the determination that was possible in a person. Phineas immediately put the phone back to his ear and answered with a voice that was no longer one of defeat but with a conviction even Isabella had never heard from him.

"I would never give up. Ever. Especially not you. You are the best thing that has ever happened to me, no matter how cliche that may sound. I'm not giving up. I lost. I screwed it up. Just because I realize that doesn't mean I have to like it, or fully accept it. But if there's one thing I've learned other than to never give up is that sometimes you just got to let go of what you love. No matter how much it hurts."

"I think you at least owe me the rest of the story on how you got to be kissing that girl at the restaurant." Phineas found the hope he had been sure was lost

"How about over coffee?" His hopefulness was evident despite him trying to repress it.

"I'll see you at 3 at Joe's cup of Joe on 4th street." With that Isabella hung up. She fell down onto her back. She wanted to scream, and cry, and a part of her wished she could just curl up into a ball and die right there. But she had to go get coffee with Phineas in a couple of hours. She knew why she hadn't answered earlier. She had spent a whole day crying after she found out. Then she finally picked up her phone to listen to the first message. After that she really didn't want to talk to him. All his first message had said was "I knew you wouldn't answer because you have no reason to. But I love you, only you, and I always have and always will. Know that whether you forgive me or not, I am sorry." She couldn't talk to him, or listen to his other messages. She had already forgiven him. She was supposed to be the girl who made fun of the dumb chicks who forgave cheating boyfriends. And here she was, after listening to one message, forgiving Phineas. She couldn't do it. She wouldn't forgive him. But perhaps there was an explanation. Other than him being the lowest form of human being of course. Eventually, and reluctantly, she answered the phone for one of his messages. And she even took the steps to stop him from hanging up. Now she was going to go to get coffee with him. She knew the second she saw him she would forgive him. And at this point that was what was upsetting her the most.

"Hey Isabella. It's good to see you." Isabella walked up to Phineas in the coffee shop not looking happy. Phineas, the optimist, was expecting her to let him down as gently as possible instead of coming here just to be mad at him. The fact she showed made Phineas feel better.

"Hey Phineas." They sat absentmindedly stirring their coffees until they were half empty. Finally Isabella looked up from hers and said "We both hate coffee so why don't we get this moving before we need new ones." Phineas wasn't really happy with getting it moving. The chances of this not ending well for their relationship were pretty good.

"Well I met her when you were in Mexico visiting your family a couple of months ago." Phineas painfully went through every moment he spent with Amanda. As well as every time he avoided telling Isabella the true about something or every time he outright lied to her. Isabella was impressed with his ability to go through it all but she kept her face looking unimpressed. Halfway through Phineas explaining how/why he decided to break it off with Amanda Isabella cut him off.

"I'm not happy with you." Phineas had a confused look on his face.

"Why?" The answer seemed so obvious that 'why' seemed like a valid question.

"Because here you are, having cheated on me, having lied to me, and having given me an 'I'm sorry' and I have to sit here knowing what you've done, and still accepting your lame excuse of an apology." Phineas's eyes widened

"Accepting? Does that mean we could start over again?"

"Starting over again means me liking you for years with no clue as to how you feel around me. Maybe we could think of a better way." Phineas's signature smile was back and better than ever but he made sure his excitement didn't get the better of him.

"I like you for years with no way of knowing if you feel the same?" Phineas suggested

"How about.." Isabella pulled him across the table into a kiss which he gladly returned with all the passion Isabella had ever felt. All the tension he had felt whenever he kissed Isabella was gone. He knew she was the only person he ever wanted to kiss because she was the only one he loved. If she could forgive him after catching him in that situation then clearly she felt the same way which was more than enough for Phineas to get the feeling of perfection in his life he had wanted.

They walked out of the coffee shop without having drunk another sip of their coffee. They were laughing and joking to the point where what had happened over the past week clearly didn't matter to Isabella. Even if Phineas's face still showed regret.

"Oh and Phineas?"

"Yes my love." Isabella smiled and replied with her normal girly voice

"Cheat on my again and I'll rip your freaking heart out." Phineas's smile didn't falter for even a second

"I guess that's fair. It has, and always will, only belong to you."
