Answer:
Stanley assaults Stella after she returns during the poker game.
Step-by-step explanation:
"A Streetcar Named Desire" is a play written by Tennessee Williams. The play is about Stanley and Stella Kowalski.
In the play, when the poker game ended and Stella returns to Stanley, he slaps on her buttocks, insulting her. Stanley assaults her as he desperately wanted her to be with him during the poker game.
Therefore, the reason that Stanley disrespected Stella is in his desperation.
