Leading someone on, then telling them there your friend?

Well me and this girl have been hanging out alot recently.....ive known her for like 6 months.....we go to the mall, see movies, go out to eat....and during this time she is all over me...like holding my hand, arm, feeling up my muscles..staring at me when she thinks im not looking, and just being idk a lot closer than a friend would and not to mention she invited me to go with her most of the time.....so i asked her if she liked me and if she wanted to date.....she told me this...."i don't want you to think im gonna be your girl friend" and she said she doesn't want a boyfriend, and she wants to be my friend really bad....i don't really get what sup i mean, after all this she drops this on me?? like what? did she just want a good looking dude to give her compliments and hang out with her to make her feel better about herself, and not expect me to have feeling for her? anyone have an opinion or have you done this to anyone? where both 20....
