Try to sound like a father, sorry i know that sounds cheezy, but I really think she's looking for that. If all she does is watch movies, listen to music, and read books (presumably novels not metaphysics texts) then she likley fantasizes alot.
This presents a problem in marriage, becuase spouses often fall short of the ideal...and often people who idealize their spouse end up hating them when they find out who you are, even if you arne't a half bad person. Its more the shock of growing up than there being anything wrong with you. Granted, I am sure you made some really bad moves. Just don't make any more of them.
I still think playing the mature father role is your best bet. I am in a much different situation, I have been criticized for working too hard and not being fun enough etc...we really need to find out what she's looking for in you..but my bet is maturity.
