Have you had this situation?

My girlfriend and I have been dating for a little under a year and a half. I love everything about her, and I think she's a beautiful person. Recently she opened up to me about her faith. I am a Christian, personally, and she tells me that she believes in A god, but she's not sure what's real.

She was raised in a Catholic family that's religious (goes to church and catacysm), but they don't really support the faith in their lifestyle. In other words, they go just because they think they have to or out of habit.

She also had a recent experience with her best friend, who became a born again Christian, but immediately after became carried away with a boy and started to become very arrogant, using her new found faith to try and win arguments, or make my girlfriend feel guilty. This is also topped with various other drama surrounding her friend's church group, acting in various inappropriate ways.

My girlfriend has all Christian qualities in her lifestyle and the way she believes to live (love everyone and everything, help others, etc), and she is plays at her church, but I feel the only thing holding her back to believe in Jesus Christ is her experience with her friends and family, who really didn't convey at all about what Christian faith is about.

At this point I've figured to love her as I feel I am called to, but at the same time, I have a fear that she may altogether reject my faith with hostility, which could result in arguments with the way we raise our children. I guess I'm just at a loss of what to do. I love her, but at the same time, I love my God and creator. Although I would love to share this love with her, I don't know how to approach it without being pushy and stuff. I just want to love her, but I'm just afraid we will have future problems with our family (should we make it that far). Has anyone else had to deal with such a situation? If you have, what did you do? Are you still together? Did it work out?

And please don't harass me on my faith. I believe what I believe, and I have every right to do so.

P.S. We have not had sex and we don't intend to anytime soon. And by anytime soon, I mean marriage.

Also I would appreciate answers from people who have dealt with a similar situation personally. I don't want any "You're putting religion before love" stuff, because I'm obviously not for the simple fact that I'm still dating her and am considering marriage. At the same time, I would appreciate avoiding answers from the polar opposite saying "You can't be together unless you're both Christians!". While I somewhat understand the logic of that answer, it's not constructive.

Remember, I'm not asking for your opinion on whether or not we should stay together. Just because a few internet junkies tell me to doesn't mean I'm going to break up with her. I'm asking for personal experience and stories. Anyone?
