what Blanche was thinking, meaning what was gong through her mind? What prompted her promiscuity? How could she have defended it? at least 3 - to 4 lines please?

Blanche was the epitome of the "old southern belle." She lived in the past because she felt she had no future; her husband's suicide left her nothing more than a shell and helped to cause her loss of reality. Her promiscuity came was caused by the desire to be loved, and maybe even moreso by the desire to retain her youth.
