My Fiancé Slept With Her in My Wedding Dress by Sapphire Dee

"I look better in the wedding dress. Your ugly fiancée can't compare to me, right?" "Of course, you do. You look way better."
Standing right outside the bridal fitting room, I watched my fiancé, Alexander Blackwell, hold his mistress in his arms.
The very wedding dress the woman wore was the custom-made designer gown meant for my own wedding next month.
For seven long years, I gave up my youth and poured everything into Alexander, turning him from a nobody into a tech billionaire.
He always thought I was just a helpless orphan who had nowhere else to go, blindly confident that I would never dare to leave him.
He had no idea that I was actually one of the heirs to the top-tier Sterling family in London.
When he finally realized what he had lost and desperately tried to beg for my return, I didn't look back.
Because I ran into Theodore Morrow—the city's most powerful, ruthless billionaire CEO, and the childhood fiancé whose heart I had broken when I called off our engagement years ago.
