How does Willy Russell portray the changing relationship between Rita and Frank in "Educating Rita"?

"Educating Rita" is a play dealing with class boundaries and the issues surrounding it, set in 1980s. In those times, class was much more important than it is now. Not many people attended universities and those who did were mainly upper class citizens. However, this play tells us the story of a young woman named Rita who challenges this system. She aspires to attend university to get a higher education, defying her working class background. …

…She's still the person she wants to be. At the end, she is able to have a healthy relationship with both the "educated" and working class communities. Although Rita undergoes the main transformation to become educated, Frank developed as well. He does have more confidence and Rita has brought his meaning of life back to him. Rita and Frank both help each other into becoming better and wiser people and are both grateful for that.
