The girl in question had been working there for a few years (I work in a lab at a school). So this girl is pretty antisocial. From what the rest of the people that work there told me, she keeps to herself usually. She usually eats by herself and rarely gets involved in conversations with others that work there when they are gathered together and talking. When she walks into the lab she pretty much never greets anyone and just sits down (she sits at the far end of the lab but passes by everyone to get there), and when she leaves the lab, she doesn’t say bye to anyone even though she passes by them. So basically, she seems pretty antisocial.

The first 2 weeks I was there, she seemed to be really flirty with me and into me. One time, I was asking one of the lab members about where I can find bookstores nearby to buy books for my classes (since it was the beginning of school). The girl joined in the conversation and when she talked to me, she was very happy, energetic, enthusiastic and had a big smile on her face and she was telling me about different bookstores and which books she recommends for my classes. Another time, I was asking some people in the lab for advice about a certain class that I had to take (that they took), and she joined the conversation, again with lots of enthusiasm and a big smile and she was giving me information and advice on the class (how to do well etc.).

Another time, I took my jacket off in the lab to work with some chemicals, and I have a tattoo on one arm. I was making a bottle of some chemical, and while I was waiting for the chemicals to mix (basically just standing there doing nothing but waiting), she went up to me and started asking me questions about my tattoo, like when I got it, did I design it myself, and she said that her cousin has one and that mine looks really nice and she likes the color. I just said thanks and didn’t continue the conversation, and she eventually left. She seemed very happy and enthusiastic and had a really big smile and was very energetic when she was talking to me.

I never really initiated a conversation with her (the only time I ever talked to her was when I asked questions about how to do something). I never made an effort to talk to her, but I talked to the other people in the lab and made friends with them. She almost never came along when me and everyone else ate lunch together. At the end of my 2nd week there, she stopped being so cheery with me and talked to me with a normal tone of voice. She also pretty much never got involved in any conversation that me and the rest of the lab were having. And if she did, she never directed any attention toward me. I don’t work there anymore, but if I see her and I say hi to her, she’ll say hi to me without a smile and no enthusiasm. But other people that worked there greet me with a smile when I see them nowadays.

So did this girl even like me? If she did, why did she start acting differently a couple of weeks later (meaning not being so happy around me and not trying to talk to me)?

And did I make the right choice by essentially giving her the cold shoulder, since it was at work? Or should I have tried to get with her?
