What to do with an undecisive friend?

I met this girl at work about 6 months ago. Right away I knew I liked her, and It was so easy to talk to her, so my feelings started to go from there. I have told her how I feel about her because we have such great communication. I also realize that there arethings about her that I don't yet know.
Turns out, she really likes to go out and drink with her friends, and they are all guys.
She reasures me that they are only friends to make me feel better, and that I am special to her but she also tells me that she doesn't want a boyfriend, that she needs time. I have treated this girls with honesty, sincerity, and respect, but things are so confusing.
2 days ago she tells me that it's better to be just friends(which is what I thought we were), but the next day she acted so affectionately as if she changed her mind.
I discovered that I don't really love her, but that I really want to be in love with her. What step do I take?
Do I risk relly getting hurt but maybe having the relationshit I really want(because she probably won't change for me), or do I back off and forget about us. I realize that no matter how hard I try, I will eventually fall in love with her, and if she doesn't change, she could kill me, so I probably cannot be her friend much longer like this. Tweet
