My Paranoid First Love

I'm Elena. My mother died when I was 10. After that, my dad married my mom's friend, who was his secretary too.
And now I'm lying on her son's arm. I never thought he would do it with me. Paul was on me while I was staring out the window of the car. He was quietly sleeping. I was stroking his hair and singing a song that had previously been recited by Mom. Suddenly, the surroundings lit up slowly. 
It was going to be dawn soon. I put my voice down. He was still clutching me tightly in his sleep. I attempted to loosen his grip.
 In anguish, I closed my eyes. My lower back and lower body were in excruciating pain. I gently put his head on the seat and smiled at him. I softly called his name, “Paul.” 
“You know how much I love you."
“But now it's irrelevant to me,” I said as I stroked his hair.
“Are you sure you love me?” 
“Then you gave me the ability to hurt you, too.” 
I kissed him on the lips right after saying. I got out of the car after giving him my farewell kiss. I didn't feel any pain.
