I met him in my tech ed class in early September of last year. His name is Tyler. He became my best friend, and my being the idiot I am , I fell in love with him. He affected every aspect of my life. My grades dropped dramatically. I changed my route to classes just so I could see him in the hallways.

One day, he kissed me. It was my first kiss. And literally the next day, I found out he had a girlfriend, Dawn. It broke me.

After a while, it got easier. And I developed a crush on Dawn's sister Karissa.

I started dating her, and my being in love with Tyler got easier.

But here's where it gets fucked up.

Thee main reason I started dating Karissa is so I could get closer to Tyler.

I feel horrible for it, and I feel like I'm using her.. Help??
