Is stellla trapped

I don't think Stella initially feels trapped. Stella Kowalski, Blanche's younger sister, is about twenty-five years old and pregnant with her first child. Stella has made a new life for herself in New Orleans and is madly in love with her husband Stanley - their idyllic relationship is steeped in physical passion. Stella is forthright and unapologetic about the nature of her relationship with her husband, and although she loves her sister, she is pragmatic and refuses to let anything come between her and Stanley. Stanely does however, end up cheating on Stella with Blanche.
