What should i do about this girl?

I can't tell you if she's interested, but I can tell you that you are definitely not being a pest, and I can also tell you what you should do. In my opinion, you should maintain a steady text conversation with her to make up for the absence of conversation between you two. Flirt with her a bit, let her know you're interested, if you do I can promise that she'll get the message, or at least an idea. Then when you're ready if all is still going smoothly and there have been no signs of her disliking your company, ask her out. Nothing too serious, start with a movie or something along those lines. Maybe even a group date with some friends if that's how you would like to go about this. I wish you luck, and hope that you 'get the girl' in the end.
