There is a good reason
Jane knew she had a good reason for marrying Tom but, since her parents decided to keep her from her, she decided that they wouldn’t know. Her heartbreak took her months to heal, and her marriage was affected.
They made it because their love was stronger.
Jane’s father
Jane did not know that her father had nothing to do in the text. He thought that Jane had been the one to never want to speak with them again.
As a loving and protective dad, he did not want to see her go. He hired a private investigator.
