So I fell for a girl. Normally this wouldn't be an issue

You're dating this girl right?
Ever thought of addressing this with her? Some people are just private; if you feel like you know nothing about her maybe you fell in love with an act she puts up.

how much time has she had to get used to you? is it a problem if she is a private person? if she isnt just a private person, she may have trust issues or be shy. Make her feel comfortable

how long have you known her? There are always going to be some things you don't know about a person, no matter how intimately you get to know each other. Hell, people don't even know everything about themselves. Furthermore, revealing your "true self" (however you want to conceive of that) to someone demands a lot of vulnerability. It could be that she's a little insecure (I know you say she's confident, but this can always be a front), or doesn't think she knows you well enough yet. In fact, it could be a good sign; I've known many people who present themselves as a complete open book when you first meet them, and yet ultimately end up being deceptive, petty, or otherwise shitty. Meanwhile, people that I've found very difficult to get to know have often resulted in my most rewarding relationships.
