Why is she like this.....?

being a girl, this gives me hope that theres still great guys out there like you. shes definitely been hurt in her life, and unfortunately guys have probably said the same things you say to her, so she thinks its just going to be another let down. or maybe shes so into you, she doesnt want to commit so early because she knows you guys are so close that youll still be there when shes ready. all i can say is text her and tell her or call her or anything and tell her how you really feel, and say it with all the sincerity you can, and then tell her youll be there til shes ready, but if shes never going to be ready, youre still willing to be there for her and act as loving and caring as you feel, but dont be clingy if she wants space. then see if she starts to soften up after a few weeks. i really hope she doesnt let someone that cares about her so much get away from her. shes really luck, good luck !
