Reps for Jaime and Turbo if I can.

I've been in quite a similar situation for a while now. I've been dating the girl going on 3 years now, and she's a fairly strong Christian. I, on the other hand, am of...shall we say, wavering faith. Long story short, a lot of bad things have happened in my life, and I get to points where I question things. Also, she was raised in one of those hardcore 'Hellfire and Brimstone' style baptist churches, and I, catholic. She tried for a while to get me to start attending her church, which I did a few times, but it wasn't for me. It was nothing like what I was raised to believe and I just couldn't get into it. The same goes for her, she's gone to mass with me quite a few times but didn't care for it at all.

The point I'm trying to make is this: though you may have differing beliefs, if you truly care for one another, rather than making it a point of friction, you'll make it an experience to educate one another on your beliefs, and possibly bring a new level of understanding with it. Use your differences as a chance to bond, not a reason to break.
