Kara
"Yes, Derek. I did," I admitted. The way he looked at me felt different. After that response, I knew I had lost Derek forever. I could never win him back. I thought about everything he had given me and everything I had taken away from him. When I arrived in Los Angeles, I found a man who was emotionally and mentally stable. He fell in love with me and took the risk of giving me his best, but I only took and crushed his feelings. My mess broke him.
I would never forgive myself for what I did to him.
"After everything, Kara... after everything I gave you, you pay me back like this! I never asked you for anything. I didn't even ask you to love me the way I love you. I thought I didn't have to ask you to respect me because I thought you would. I thought you were different. You did the same to me he did to you. You're no different from Stefan. I don't know why you complain about him when you're just like him."
