Yes, obviously she favors you, she is giving fairly low-key clues to signal that she's interested. (At the least, not adverse -- but I think very interested, as you've already said. I would do all the stuff she was doing at the concert to show I was interested. Touching someone is usually not an accidental thing, unless you see her touching EVERYONE. Especially with introverts -- there is a certain "space buffer" people keep around themselves, esp with members of the opposite sex + you have the religious thing going.)
Wow.The church I attend takes courtship very seriously. I'd need to get her father's permission to date her, but she's a convert--making our pastor her de facto gaurdian. And neither of us has been properly vetted to ensure that we're ready for the responsibilities that come with marriage.
Well, all right then.
I just think when people like each other, they want to put out signals showing it. She's giving you signals right now that are within the acceptable parameters of your (plural) faith. If you can give her signals back that are within the acceptable parameters too, go for it. I think she would appreciate it. I think if you don't give her SOMETHING to go with, she might not be sure after awhile if you're interested. So just enough, subtle stuff, to key her in and reaffirm it.
Since you take your faith very seriously, however, you just do have to make sure your signals stay within the acceptable parameters and you're not strenuously fighting not going further all the time. That's all.
