If a girl makes eye contact and smiles really wide when we talk, does it mean anything?

I've been talking to this girl for a while now. She tries to act tough and sarcastic with me, but she is extremely easy going to other people. Recently I've noticed that when we talk, our eyes will connect and I can literally, she the muscles on her mouth move to form the biggest smile I've ever seen, seriously, its kinda like she is smiling in slow motion or something lol. She teases me a lot though, usually telling me I talk to much or to be quiet for one second or that I'm being annoying and I will kinda turn away from her but I can hear her she is trying to suppress her giggles when I'm not looking. Like I said she gets along better with other people but I get all this hurdles, what's up with her?

Even though it seems that any other person (guy or girl) gets better treatment and a friendlier version of her? I guess the smiling would be a giveaway, but she kinda makes it hard for me to talk to her, because she keeps telling me to go away and makes it seems she doesn't enjoy anything I do (she does it smiling, but still)

Wow, it seems pretty unanimous haha. I know it may seem obvious but the whole "im not nice to you but I'm nice to everybody else" approach throws me off. She doesn't seem as nervous as she was when we started talking. Also, she is a shy girl so that may explain some of her behavior bit still, pretty confusing.
