Describe an external conflict that Jeannette's father experienced in the story

As Jeannette matures she begins to understand how her father continually lets the family down. Once the only child who believed in him, she loses hope in Rex as his drunkenness worsens. In part 3, When Jeannette asks Rose Mary to leave Rex so that the family can qualify for welfare, Rose Mary is shocked and she admonishes Jeannette for losing hope in her father. By this time the illusion of the "Glass Castle" has been shattered and Jeannette no longer respects Rex as a father or provider.
