What is the difference in Mr. Loomis from when Ann first meets him and the end?

Ann is a good person who helped a man in need. Ann welcomes Mr. Loomis into her valley, after a bumpy start, and is willing to share everything with him. However, Mr. Loomis decides that he must take charge, stop Ann from doing as she pleases, and treat her like a possession. It is this behavior that ends the relationship between Ann and Mr. Loomis, leading Ann to steal his suit and run away.
