Describe the character of Dorothea as a conversational Victorian heroine in George Eliot's Middlemarch

Dorothea Brooke is the oldest of two daughters, and raised by her bachelor uncle, Mr. Brooke. Dorothea is an excessively religious, pious girl‹to the extent that she withdraws from the activities she likes most, and convinces herself to marry a man, Mr. Casaubon, who cannot satisfy her emotionally or mentally. Dorothea, although she is fairly well-educated, is naïve about the outside world; when her marriage disappoints her, she is forced to learn that she cannot make a life through other people, and that she must fulfill her purpose in life through her own effort.
