"Breaking her promises as per usual, she puts herself, her fame, her reputation, and her bank account before me. If she really wanted a relationship she would keep her promises and recognize that it is no one elses fault but hers that I do not want her in my life.," Sidney wrote in a post that has since been deleted.
