Which sentences in these excerpts from kate chopin's “the story of an hour” reflect the theme that marriage limits a woman’s freedom?

There are many quotes from "Story of an Hour" that reflect feminism. All you have to do is look at the end of the story. But here are a couple:

"There would be no one to live for during those coming years; she would live for herself. There would be no powerful will bending hers in that blind persistence with which men and women believe they have a right to impose a private will upon a fellow-creature."

"And yet she had loved him--sometimes. Often she had not. What did it matter! What could love, the unsolved mystery, count for in the face of this possession of self-assertion which she suddenly recognized as the strongest impulse of her being!  "Free! Body and soul free!" she kept whispering."

"Her fancy was running riot along those days ahead of her. Spring days, and summer days, and all sorts of days that would be her own. She breathed a quick prayer that life might be long. It was only yesterday she had thought with a shudder that life might be long."

Hope this helps :-)
