Wlizabeth Englin was not the Betsy he remembered
When Grady arrived in Chicago he didn't expect to find a woman managing the prestigous Englin Hotel--certainly not the 1 woman he remembered w/ nothing but bitterness.
As for Elizabet, th elast thing she wanted was to see Grady again. He stirred up too many memories & brought back too much pain. She had built a life to her own ssatisfaction & it was centered firmly on the hotel & her small son.
So why wouldn't Grady go away & stop tormenting her for things that had been his fault?
