<human>: Can you give me the gist of the text in a nutshell?

So last week I asked a girl from class to go to dinner with me. We got coffee together everyday that week after class and then on Saturday we went out to dinner and then back to my place to watch a movie. It was at this point that things got uncomfortable. I was trying to read her body language to determine what she did and didn't want to do and she wasn't giving me anything. She just sat there with her hands in her lap. We still talked throughout the movie and laughed and made jokes but I just kept waiting for her to give me the OK to take her hand or put my arm around her or something. After the movie it was pretty late so I took her home. She said she had a good time and wanted to plan out another date, but now when I'm around her I feel like there is a tenseness that wasn't there before our date on Saturday. Does anyone know what might be going on or what I could do to fix this? This is the first girl I've been interested in in some time and I don't want to mess it up but I feel like there might be some confusion as to what is happening between us. Should I just talk to her about it, or is it too early to have that conversation? Sorry if I rambled at all, I just don't know what to do.
<bot>: Went to dinner and a movie, girl gave me no physical cues whatsoever but still seems to like being around me. Is it too early to talk about what our expectations are?
