After Ruth meets Dennis, what big change does she make in her life?

Although Dennis dies when Ruth is pregnant with James, he changes Ruth’s life.

He had a difficult childhood. In New York City but overcame his obstacles. He was a violinist and brought music into Ruth's life. He was a kind man who gave Ruth the devotion and sensitivity she never had. Dennis was a devout Christian who guided Ruth to a new sense of purpose and life.
