How do I not mess it up with this girl?

I have been seeing this girl. I really like her and she has let me know that she likes me too. We have been together a few times and I really thinking I am falling for her. The way her situation is though its really hard for us to see each other. She is afraid of letting others around us know at this time that we are more than just friends. When I am trying to be a friend with her and talk to her normally she gets weird with me and kinda pushes me away. When I try act like more than a friend she gets upset and pushes me away. I am very straightforward and let her know how I am feeling about everything and how I feel about her. She says that I am pushing to hard and that I should let things come naturally. I am just not sure what do, if I give her a little bit of space she says that I am acting weird and when I try to act friendly with her she says I am pushing to hard. I am just not sure what to do about the whole situation. How do I show her how I feel without making her feel like I am forcing it. Please help, I am so confused.
