Your pov:
my daughter Samantha was bouncing on the trampoline. When I saw....the impala I knew it anywhere the familiar purr.

"Sammy comes on let's go inside," I tell her.

"Why?"

"Its time to go inside honey that's why." I help her in as quickly as possible. Hoping That dean didn't see us.

I go into the bedroom. "Honey!" I say.

He was on the bed taking a nap.
"Hm? What's wrong?"

"I saw the Impala outside."

"Did you think he saw you?"

"I don't think so."

Right then there is a knock on the door.

I ran to the door and there stood Dean.

"How can I help you?" I asked.

"Does a Sam Winchester reside at this residence?"

"Who's asking?"

"Where the hell is he?"

"Who's asking?" I say pushing on the question.

"Lady I'm going to ask you one more time where the hell is he?"

"I'm going to ask you..one more time whos....asking?"

"I don't have time for this." he pushes the door open forcefully causing me to fall.

"Sam!" I yelled.

He came rushing in and dean punched him in the face.

"Dean what the hell is your problem?!" Sam yelled.

Dean grabbed him by the collar."Dad died and you weren't there dammit! and he used his last breath to tell me to protect you that's what the hell is wrong with me! You decided to run away with some chick when Dad and I needed you the most!"

"Dad wanted me to keep risking my life when I wanted to go to college a lot of parents would've been proud but he wasn't!"

"Its family business sam you are supposed to give up your dreams to help and save people but you wanted to be selfish!"

I sat on my knees and clutched my stomach listening to them fight not only sam and dean but the ones in my head telling me to leave.
Telling me it's my fault.

Saying I should die.

I felt pain strike my heart and tears sting my eyes.

"You were always daddy's soldier he didn't like that he couldn't control me so he let me go!-"

"Please stop! Stop it stop yelling!!" I scream.

"Mommy!" Samantha cried.

I turned to her. "Hey, baby girl mommy's ok just go back to your room ok?" I say smiling at her through the tears. She goes back to her room.

Dean turned away from Sam and looked at me.
"You..."
He said menacingly." you tore this family apart! You took him away from us!!"

He continued to yell but it was all inaudible.
Sam got in front of.
"Dean leave my wife out  of this-this has nothing to do with her!!"

I couldn't take any more of the yelling and the blame.
I got up and ran out of the door as fast as I could.

Sam's pov:

"Dammit Dean what the hell?!"

"It's not my fault shes soo damn sensitive!"

"She's three weeks pregnant and battling depression dean she's really unstable she'll probably try and kill herself!" I get my keys. "I swear if I lose her and that baby I will never forgive you!" I tell him. I get Samantha and get into the car.

"Daddy where's mommy?" Samantha asked with tears in her eyes. She's seen her mom go to the hospital for a suicide attempt already shes literally scared of losing her mom.

"Honey we'll find her don't cry." I try and reassure her.

Soon we come across a bridge to see (y/n) sitting along the side crying. I stop the car.

"Stay in the car sam," I tell her.

I get out and rush to (y/n)'s side and sit her on my lap and she cries.

"Please don't scare us like that please don't!" I tell her as I stroke her hair and rocked her.

"It's my fault he's right I'm a monster I tear families apart! If I had never agreed none of this would've happened."

"No, it's not your fault." I kiss her forehead.

I hum her favorite song and carry her into the car Samantha cuddles her.

I go back and see dean on the porch. I carry (y/n) in my arms. Dean gets up and opens the door.
I and Samantha go inside I put (y/n) on the bed. Usually, after these moments she needs her sleep.
Samantha goes to her room.
So it was just me and Dean in the living room.

"Sam I-"

"You don't understand? yea, you don't (y/n) suffers from depression because her dad used to abuse her when he got drunk. She can't handle pressure and get well. She's super sensitive she sometimes blames stuff she has no control over on herself. But she is my life I refuse to get caught up in the hunter world anymore I've finally got out and I'm not going back in. I'm sorry that dad died I am but I'm not gonna start hunting for revenge."

"Sam I'm sorry." dean said

Right then (y/n) came in with her hand wrapped around herself. 

"You can say whatever to me I don't care... but never attack my wife," I tell him.

Dean looks at her."(y/n)? I'm so sorry for what I said I didn't know that you were pregnant." he said apologetically.

"It's fine." (y/n) said shyly
She stands beside me.

"Three weeks?" dean asked.

She nodded and smiled.

"What are you going to name them?"

"If a girl Mary kay Winchester. Boy Sam didn't like it at first but if a boy Michael Dean Winchester."

I roll my eyes. "I wasn't too keen on it at first but I've grown to love it."

"May I?" dean asked.

"I don-" I started.

"Its ok Sam, you won't find anything but a small baby bump," she says smiling as she lifted up her shirt to reveal a small baby bump almost unrecognizable.

He placed his hands on her belly.
"Hi there I'm your um uncle dean." he started crying "and I'm sorry for all that pain I must've caused not too long ago. That won't happen again because I won't bother you again."  he said.
He stood up and head for the door.

"Wait, Dean!" (y/n) called and he turned around.

"I don't want you to go. I want you to be apart of the family the
Just try not to be violent." she said smiling.

He smiled and they hugged.

"Well, sam at least you chose a good one to run away with the runaway with," Dean says smiling.

I did.

In the end, they had two kids and Dean found a girl of his own and they both lived the apple pie life.
