Hi, I'm Cassie. I'm a twin and my sister and I have always been close, but recently she's been acting strange. She won't tell me what's going on, so I came home to confront her. Unfortunately, when I got here, she wasn't alone.
My sister has been seeing someone behind my back, and now that person is in our bedroom with us. They must have heard me come in because they quickly tried to hide under the covers, but I saw them anyway.
I knew right away what had happened - my sister had been cheating on me with this person for months. It hurt so much to find out, and I was angry and upset. But also, I felt betrayed. We're twins, and we promised each other that we would always be there for one another no matter what.
I don't know what to do now. My sister won't talk to me, and this person who hurt her so much is still in the room with us. I feel like I'm caught in some kind of nightmare.
