Reclaimed By My Ex-husband

"I want a divorce," Nathaniel said with no emotions.I was shocked at how callus he could be. I didn't get a chance to tell him about my pregnancy.After five years of marriage, I still couldn't warm his heart. I understood I would never be able to replace my sister in his heart."Fine. Let's divorce then."~~~~~~~~~~~~~I, Zara Moore, married my brother-in-law to fulfil my dying sister's last wish. I poured my heart into this marriage, cared for him, and loved his son like my own, hoping that one day, he might return my feelings.It was only my wishful thought. I ended up being killed in my past life.Reborn, I could see the truth clearly.To him, I was a promise he made to his first love. Tired of being just an obligation, I decided to leave him and not tell him about the child in my womb. But with tearful eyes, he pleaded for one more chance.~~~~~~~~~~~"Don't bring up divorce," Nathaniel growled, his cold gaze fixed on me."I am done with this emotionless marriage," I retaliated."What about the promise you made?" He hissed, squeezing my arm.I gritted my teeth. "I tried to warm your heart for five years, but I failed. I don't want to keep doing this."His expression changed, his eyes pleading. "Give me a chance. I'll make up to you."I stared at him, stunned. He clearly didn't love me. Why was he unwilling to let me go?
