Whats your opinion? Need answers ASAP!?

Me and my gf have been dating for a while now, almost a year. She is a good Christian girl. We have known each other for 12 years. Im a guy who likes the chase when you get with someone, but ever since we started dating, she has done everything I ever asked, no questions asked. Basically, I feel as though she does not have a backbone anymore. She has even sacrificed some of her Christian morals to be with me. Im a Christian also, and it really bothers me. Im getting mixed answers from friends who know her, and i need a neutral opinion. I want a girl who has an opinion, makes me chase her and keeps me interested, but if I broke up with my gf, she would be heart broken. She wants to get married ASAP, I want to wait a bit to see if I actually want to be with her for the rest of my life. What should I do? And please dont just say sit and talk with her, cuz i've tried that, twice.
