In what way does Higgins show his lack of respect for Eliza and his failure to realize how she has changed?

Higgons shows Eliza a lack of respect when he blows off her concerns and tells her to take a nap. Then to top it all off, he says that maybe his mother can find her a husband, which Eliza equates with selling herself. She then reminds him that she wouldn't sell herself when she was a poor, working class woman..... she certainly wasn't going to sell herself now.
