Betrayed by my own blood
My brother tried to take one of my girlfriends I had. I met her when I fell off my bike. Her mom and herself brought me in their house to rescue me and treated my wound. After that we got closer and I eventually got my first kiss. My brother on the other hand finds a way to talk to her behind my back. I was crushed. I blamed her instead of him. Betrayed by my own blood.
