The Hot Zone, Richard Preston.
The right answer is the second option. Logan is expressing his opinion about Janie’s rejection feelings. Based on his speech and the conversation context, Logan seems to be a working class person, whose education may not seem enough for Janie’s parents or whole family’s standards. Also, his exclamation in the second part, when crying, it can be noticed that he implies to be upset with someone, in this case Janie. So more than hating her family, his feelings on her rejection due to his social status wins over. Just to add this fragment comes from the book The Assertive Woman in Zora Neale Hurston's Fiction, Folklore, and Drama by Pearlie Mae Fisher Peter, in which she relates the struggle of African American society and how wrong assumptions on social classes caused Logan and Janie relationship not to be acceptable at that time.
