Ok, I don't want to sound bad about this but this sounds like a high school thing. Also you seem a little obsessive about it, posting her pic and all. That's not good.
Just ask her out man. There's no other way to put yourself at ease unless you face it head on. If it works out, hey, all the better. If not it is a learning experience.
If you don't get up the courage maybe one day she will never come back. You'd end up regretting it for the rest of your life if oyu think something could happen.
Maybe she would like to get with you? She did goto church twice in one day

Above all else just keep an open mind about things.
Oh yeah, and why the hell are you sharing this with this crowd? No friends by you that you can talk to, that would help out too.
