What do the narrator's statements above reveal about her?

Therese is a major character in the novel and one that the story begins with introducing. She owned a large mill and a plantation after her husband died. A man called David Hosmer who lives in her plantation falls in love with her but she makes the wrong decision and advises him to re-marry his wife. Therese is known as the advisor of most of her friends and acquaintances, and anyone who needs help in a decision or in any matter would probably go to Therese. Although she appeared as a strong woman with no emotions able to affect her, it is known throughout the story that Hosmer's insistence on her love was her weakness. Also, though Therese is known for her helpfulness, the advice she had given David was negatively life changing.
