I gave him my heart, and he took and pinched it to death; and flung it back to me. People feel with their hearts, Ellen, and since he has destroyed mine, I have not power to feel for him.
I gave my heart to him, but he hurt me deeply, crushing it completely and dismissing it without care. He took what I offered sincerely and cruelly damaged it, leaving me emotionally broken and unable to love or feel for him anymore. This highlights the intense pain caused by betrayal and the vulnerability involved in loving someone deeply.
People experience their emotions through their hearts, and once that heart is shattered, as Ellen describes, it becomes impossible to continue feeling for the person responsible for the hurt. The quote emphasizes the deep emotional scars left by such betrayal and the lasting impact on one's capacity to love again.
