Bunner Sisters Part 2

In the second part of this story I was left feeling confused with the character Ann Eliza as a whole. Throughout the whole story thus far the reader has every reason to believe she is deeply in love with Mr. Ramy, but keeps it quiet. I think it is a very respectful thing to do because of the obvious feelings her sister, Evelina also has towards Mr. Ramy. However, when Mr. Ramy chooses to ask Ann Eliza to marry him she is quick to refuse. As Mr. Ramy prepares to leave he tells her to think about his proposal only to receive the answer of "Oh, no, no. It ain't any sorter use, Mr. Ramy. I don't never mean to marry" (202). Shortly after her refusal, Mr. Ramy asks Evelina to marry him and she says yes. Ann Eliza dramatically changes from desiring to be with Mr. Ramy to happily allow him to marry Evelina.
What surprises me the most is that it appears any feelings Ann Eliza may have toward Mr. Ramy have disappeared upon hearing of her sister's engagement. They not only seem to have disappeared but she seems to feel no sadness or betrayal. Her emotions throughout this story are rather puzzling. Though she has shown many sorts of emotions, it seems a contrast that if feels such as her love for Mr. Ramy can vanish that quickly, maybe the case is that she really has no feelings or emotions.
