Letting Go of What Was Never Ours

My childhood sweetheart has aplastic anemia and desperately needs a bone marrow transplant. His brother agrees to help, but there's a catch. "I can save him, but you need to marry me." My lover ultimately dies because of medical negligence. I'm heartbroken but still marry Martin Steinfeld per my promise. During the wedding, he gets on one knee before me. His gaze is loving as he says, "I'll treat you well for life, Audrey Lynch. I'll be a thousand times better than Henry; I won't let you shed another tear." I look at his face, which is so much like Henry Steinfeld's. I believe him. Three years after our marriage, I'm five months along when I stumble upon Martin with his mistress. He wraps an arm around her and sighs. "She still can't forget about that dead guy despite us being married for so long. She's not like you, who only has eyes for me. "If not for her insisting on marrying Henry and ruining my future, I wouldn't have had to take my own brother down so much earlier than planned." My blood runs cold, and I tremble all over. Hatred consumes me, and I only have one thought—I have to destroy Martin!
