Girl Help? - Casual Discourse

It worked! YAY!

Yesterday, she went with me to get coffee. I saw her on my bus. We had similar start times at work. But she moved away when I put my arm around her. Also she asked what I was doing whenever I touched her. She didn't talk much and when she did she mostly just talked about work. After she sat down I asked her if I could have more pictures of her. She looked really scared. She said later, just eat now. So I couldn't get any pictures .

How can I get a second date? Or make her be my girlfriend?

She went once for coffee. That's a coffee date right?

Do you think she just went with me because she feels sorry for me and she doesn't really like me?

What if she doesn't want to go again?

I think she didn't enjoy going out with me because I touched her on the shoulder like two or three times and I also asked for pictures and she didn't want to give me some even though she used to let me take pictures of her. And she was really quiet except about talking about work related stuff.

So main point: How can I get her to go on a second date? Become my girlfriend. We already had our first date. But I'm not sure if she wants another one.
