Poor Ginny. How would her marriage have turned out?
I think she was really happy and would have eventually gotten some smarts and skills and become a decent little housewife and been happy tending her garden and home and having some kids. Maybe Dave would have realized he had a little gem and sobered up some and worked on his writing.
I thought Ginny was supposed to be every man's dream girl: Good Natured Prostitute With A Heart of Pure Gold. Look at her! Loose, sexy and easy, but sunny, happy, optimistic. (Like Marilyn Monroe was shown to be, in movies, a little.) Ginny is supposed to be appealing to men because she is childlike, yet sexy and adult of course, but so free and uninhibited she 'doesn't know' she's sexy. That's what men like. Not those hardened, damaged old pros you see in movies who pay for their sins, not those frigid beauties like the schoolteacher, but playful giggly gals who would walk around the house nude except for high heeled mules and a tiny apron. Tee hee! Oh, Dave!
