Disclaimer: I don't own PNF

I apologize for such late update.

The next morning, Ferb woke up and got up quickly putting on some of his sweat pants.

"Scarlet, is Isabella awake?"

"Yes, sir she left last night with Fred and Xavier. Amanda is at her room still sleeping."

"What do you mean Isabella is gone? She took both Fred and Xavier with her?" Ferb repeated running to his best friend's room. He found a folded note on her bed.

Hi Ferb,

If you're reading this then that means I already left. I brought Xavier and Fred with me. You're probably wondering why I left but that's easy. I don't know how much you've paid attention before. It's probably very stupid of me to say this in a letter. But I don't love Phineas, I never did. Okay I love him, but more of a brother rather than a lover.

I've experience a love that I can't explain. This man whom I've known all my life, I'm not sure when I've fallen in love with him. But now, I'm too late. He's engaged. Have you ever felt a love that caused this much pain Ferb?

I'll be with Phineas I just want to get away from a bit.

Isabella

Ferb crumpled the paper in his hand and just laid on the empty bed unsure with what to do. He knew the pain that she felt. He felt it too when he was young as he watched Isabella pin over his brother day after day and year after year. He stood at the sidelines making sure that those two would always be together despite feeling the pain in his heart. Then Vanessa came along, she made him forget his feelings for his best friend. She loved him through his ups and downs that's why he proposed to her last night.

"Ferb, honey?" Vanessa called out, Ferb could hear her steps getting closer.

"In here,"

The beautiful brunette entered the room and laid in bed with her fiancé. She felt something was wrong and forced the young brit to look at her.

"What's wrong Ferb?" She mumbled kissing his cheek.

"Nothing, just thinking about something when we get married," Ferb replied, Vanessa giggled and straddled his waist.

"What is it?"

"Well, I was wondering. How do you feel about being a mother?" Ferb said tucking a strand of her hair behind her ear. Vanessa looked down at her and frowned, "What do you mean?"

"With the adoption of Fred, Xavier and Amanda. I'm a father and the kids would need a mother with a stable home. I was wondering what you thought of that," Ferb explained but when Vanessa said nothing he knew the answer.

"Do you even love me?" He muttered softly, praying in his mind that he would be wrong. Vanessa got up from him and cried.

"When?"

"Last year when you left for your business conference we had a big fight and we broke up. I found someone. He was there for me when I needed someone. I've been seeing him for almost a year now. I wanted to tell you last night but you asked me to marry you and I thought that you were the right choice," Vanessa explained letting more tears fall down her face. Ferb didn't spoke once, he got up from his bed and spoke, "Scarlet, take Vanessa out of the main frame list of guests. She will not be coming back here anymore."

"Very well, Ms. Doofenshmirtz please exit the premises," Scarlet said. Vanessa sniffled, taking off the diamond ring of her finger and placed it on the dresser.

"I'm sorry Ferb," she muttered before leaving. When she was gone, Ferb took a large breath trying to compose himself as Amanda's door opening up.

"Uncle Ferb, I hungwy," she mumbled rubbing her eyes. He carried Amanda in his arms and walked down to the kitchen to find cereal and milk.

"Where's Isabewa?"

"She's with Uncle Phineas with Xavier and Fred. They're going to sleep there for a while." Ferb explained kissing the top of her head.

Isabella woke up the next morning her eyes tired from the late night crying. She found Fred and Xavier sleeping soundly in their cribs that Phineas had set up for them.

"Knock, Knock"

"Come in," she voiced out.

Phineas came in with a plate with all of her favorite breakfast. She sniffled and gave him a teary smile. She took the plate from him and started munching on the egg that she scooped up. Phineas took a deep breath in and started, "Isabella, you have to talk to Ferb. You have to tell him. He has the right to know."

"What do you mean? He has a fiancé Phineas, I can't tell him knowing that my heart will just break and I can't handle another broken heart. I can't…" Isabella told him softly playing with her food. Phineas put an arm around her and gave a soft kiss on her forehead.

"Izzy everything will be fine. Trust me," he replied knowingly.
