<human>: Can you give me the gist of the text in a nutshell?

So I have known my friend for about 4 months now. And we have gotten to know each other quite a bit. 
She is a introvert, meaning she does a lot things independently and enjoys her personal space. 

She is a senior and I am a junior in high school. I am one of her only friend she hangs out with. I can tell she is interested in me as well, but sometimes I receive mixed feelings from her maybe due to her personality? 
I have never had any experience dating a introvert. So some feedback would be appreciated. How do I move on to the next step without messing up our friendship?

I am also limited to dates because we both don't have our license. But I plan on getting it ASAP in the next month because I think it will improve my chances.
<bot>: I have known my introverted friend (17F) for 4 months. How do I (16M) start a relationship with my friend without messing up our friendship. She gives mixed signals but could be her personality?
