Why?

Hi. I am Cory Smith. I am like your typical high school girl. I am the head cheerleader and the most popular girl in school. Behind closed doors life is not always the same for me and my family. My parents are going through a big divorce that hasn't been settled in over 3 years. My mom is tired of fighting but my dad won't give up. He doesn't want to leave us. I asked my mom and dad everyday why and the never have an exact answer. They say I am too young to understand but I don't know why. My mom had no hesitation of telling me about my period and surely didn't hesitate when it came to dating boys. Why? Why, don't I understand this world anymore. I just dont get it anymore. What happened 3 years ago between my mom and dad and why won't they tell me anything.
