What is up with this girl?

Don't go for it!!!!!! I'm a girl and hate to say it but i've done this many times and its wrong...she comunicates sexually, which means its easy for her to get through to people through attraction. From what it sounds like, your the ideal 'nice guy' and though your the type of guy every girl wants to marry when it comes to dating everyone wants the thing they can't have. She feels comfortable and safe around you because your no threat, but watch her, she loves the attention you give her and she wants the other guys to see that. There always is that posibility though that she does like you and is trying to be aloof
