Should I stay or go?

All i need is Family.

One night a boy went to the wood to decompress from his stressful day. he was thinking about what had happened at school and how devestating it was. That day his best friend died and his baby brother was born. it was a horrible but happy day, the boy's best friend was a great family friend.. So in honor of him the boy's mother named her newborn son Chris, the boy's best friend's name. Once he got to the wood he saw his best friend waiting there for him he was confused he was dead and you cant comuticate with the dead or can you...... the boy slowly walked up to boy and Chris screamed with his eyes flipping backwards in his head, the boy ran and didnt stop. he saw a girl he did not see the girl before and the town only had about 90 people so she had to be new. the girl looked like his new baby brother, like a twin but his age. She said " Hello my name is Shelby. I ran away were am I?" the boy was surprised, no one really comes here. No one! So they walked to his house and every one was asleep and they walked in they went up stairs and talked for a long time. She couldnt remember much about herself or anything actually. The only way she knew her name was because she had a necklace around her neck that in cursive said "Shelby." They had to wake up early so his mom did not see them they stayed up until 3 am and then he had to walk her to the old tree house and left her with food and water to get through the day. the boy went back inside and acted like he was asleep so his mom wouldnt be suspicious. he got up at his normal time at 5:15. he heard his baby brother screaming and crying, he went to see what was wrong and screamed at the sight. he saw his mother's throat slit and blood gushing out and saw a tall man in black jumping out of the window he left a note it read "meet me in the woods or the same will happen to the baby and dont call the cops." the boy was scared, he grabbed his brother and held him for a little while, Shelby came in and saw the boy holding his brother standing at the corpse of his mother. Shelby was in tears and ran over to hug the boy she whispered "I'm sorry, but..." "But what? " the boy asked... "I couldn't let her find out" "Find out about what?!" the boy asked. "My old life and my dad and who i was." ,."What?" "When i was little my mom and dad got into a huge fight because my mom found out my dad was doing drugs and gambling. then she was so mad she divorced him and left me with him. i lived with him for 10 years until i was 14 then ran away, i did not know where my mom was but i was determined to find her. I heard about her in this city and that she went by Elizabeth O'leary instead of Liz Bailey, my dad's last name, but i had seen the pictures and it was her." "Wait. My mom was..." "yes, my mom too" the girl chimed in. "wait so who was that man?" "that man? my dad." thats when they had to take care of Chris as if he was theirs. They went out of town and went all the way to his grandmas house in colorado and stayed there with no problems for two years then he showed up...... he once again came and killed his grandpa that time before he got to the grandma he saved her so they got out right then. they ran and kept running the boy asked the girl why he wanted to kill everyone in his family, like his mother. Shelby said it was because he was so angered with the divorce he wanted revenge. the boy asked why the man wanted him to meet him in the woods. Shelby answered "thats where your mom and my dad met."
