Why Not Just Conceive a Child with Someone Else and Then Reconcile?

Half a year after I left home, I rushed day and night to celebrate my wife's birthday, only to learn that she was three months pregnant. She had an affair but remained aloof, and even demanded that her unborn child inherit my family business. I am determined to divorce my wife. After she married someone else, she regretted it and begged me frantically to save her. But I already want to marry another person, and I am about to reach the peak of my life, and I will never look back.
