I would really like to know if she likes me. I am a rather reserved person?

This girl I like sat next to me on the train one day. I started talking, and she continued the conversation, talking even more. She said she doesn't know anyone in our village. The next time I saw her, it was very late—around 11 pm when we arrived. She kept talking until the point where our ways parted. She sometimes laughs, but she's mostly serious. With some jokes, she doesn't seem to get them, and I fear she might think I am stupid. So far, we've talked about college, family, books (which she seems to be really into), etc. I've talked to her a few more times, but she never starts the conversation. She once walked right past me.
