Writing in crooked lines

The days go by and I channel all my energy into writing my book. I don't look for Tiago or Sandra. I conclude that I need to get away from them for a while to think about what to do. Calmer, I realize that even the problem with them is my fault, I brought Tiago into Sandra's life, so I'm to blame for the two of them being together. But I don't want to think about that, I need to focus on writing my book and publishing it before people lose interest in my case.
