<human>: Give me the gist of the text in a nutshell

Grad student here, wrapping up my master's as is she. We go to the same school, I met her at a bar through a couple of mutual friends. After seeing her a few times afterwards I asked for her number. I texted her a while back telling her that we should hang out more, she agreed. I took her out to dinner last week at a local spot. The conversation went really well, and we made plans to grab food again at another point. Fast forward to tonight, we went out for a second time and things went well, but I cannot gauge whether or not she's into me, shy, or just disinterested. 

I'm a very observant person, and I pay attention to body language when talking to anyone. I know the very obvious body language of girls when they talk to guys they're interested in (playing with hair, leaning in close, laughing at my shitty jokes, etc.) But I was taken back a bit tonight. While she did some of the things I mentioned before, she did come off a bit as shy. When I would make eye contact with her sometimes she would look off briefly before speaking. While I'm not having a moment of self doubt I'm not sure if she's into me, very shy, disinterested in me, or a combination of any of them. There is a chance that I could be overanalyzing this to death (a personal flaw that I'm working on deeply). Any help with this quandary from /r/relationship_advice is greatly appreciated. Thanks!
