So you feel the need to attack your girlfriends opinion because she's into romantic gay bullshit like any other girl?
And THEN you want her not to get mad at you.
Lmfao. Must be your first girlfriend.
Go read the fucking book and see if it's bad as you think first of all.
Assuming your one of the people who feel the need to reject anything if they feel it might effect there "manhood" which if you think that, then its already being effected.
Worst case scenario you have to pretend to like it and you get laid.
