Hmmm. It seems like the solution here is to ask her to go somewhere with you not related to your religious activities, and where other people you know aren't going to be around.
If she still has just as much fun with you doing something not related to what you guys usually do, and she still acts the same way, I'd say it's a pretty safe bet she likes you. ^_^
There's always the chance she really likes you, and doesn't really realize it herself yet. In that case, still do what I said, but try to play a little harder to get by getting her to chase you a little, could make her realize that she likes you.
And I have a girlfriend, as most of you know (she even posted a couple of times), and she's just awesome.
Very much like me in terms of tastes and beliefs (except for music, we like pretty different kinds of music in most cases).
We live together and do geeky things like play video games all the time.
We recently got a Kitten to, which you guys have saw. I have some new pictures I've taken that I need to upload, she's grown a lot. She's still a gamer though, she likes to sit in my lap and watch me play TF2 before she falls asleep.
EDIT: Something else interesting, last night my girlfriend was playing with the StumbleUpon plugin, and she stumbled upon....GameTavern! I was actually the person who added it to the stumble upon database, so that's pretty random and awesome.
