Does my crush like me?

I take tutoring. I am really tight with a teacher there and she is really good to me.( not my crush LOL) i first saw my crush in lobby of the tutoring place.. We exchanged looks and smiles but couldn't talk because i was already almost late for class.. I later found out that she was the niece of the teacher i know. The teacher came by to pick me up for church one day and was surprised to see my crush (and teacher's daughter)there waiting. We sat together in the car and we drove off to church.. That's when i knew she was really shy.. I don't think she's normally shy because she one of those girls who like to communicate via facebook texting and whatnot. Also likes to shop :P. So we sit together in the sermon but really don't strike up a conversation. I ask her about what classes he's taking, how long she's been at dallas but she just answers my question with fewest words as possible lol.. After sermon ppl break up into groups where we talk about the sermon. During prayer, she would look up at me and when i saw her, she would twitch her head back down like she never did(so cute ha ha).. The next day, i tell her hi with a smile and she looks as if shes taken aback and quickly says hi back. Yesterday, the teacher's daughter, her guy friend and my crush were supposed to go to a movie together but my crush didn't want to go. I visited their house to borrow Internet and said that i wanted to go and persuaded her to go too, without effort she accepted :) . Te ride there, she was acting even weirder than usual.. She would show everyone pics of food and ask questions like "why are there lines on the road?" lol!! She wouldn't even look at me siring the rode and only look at her phone texting. It seemed like she was suddenly notinterestedd in me, not walking next to me, talking to me or even acknowledging me. because lately she seemed so distant (and also there were others) i couldn't even strike up move. Alright, plus when I chat her up on facebook, she is even more distant and it seems like she wants to end the conversation and seems uninterested. Why do you think she is even more distant in chat? How ask her out? Does she like me? Thanks guys
