Write about someone who is estranged.
The post bragged that he was now with someone better. I wondered if she knew just what she had gotten herself into. I seriously thought about warning her. In the early days it was all sweetness and light, a heady mix of romance and adventure, of love and good times, until his dark side emerged. Then the fun stopped. I escaped, but who knows where it may have ended if I hadn’t, I am sure others have not been so lucky and have paid the ultimate price. Inwardly I wished her luck, I knew she was going to need it.
