<human>: Met and started talking to this girl at my high school a few weeks ago. We only have one class together and don't see each other during the day.

She is very nice to me when we talk in person. She choses to sit right next to me, compliments me frequently and etc. I have taken this to mean that she could be interested in me. I should note that I have never had any experience like this before. I am a fairly good-looking guy, but I have moderate-severe social anxiety.

Anyway, I want to get to know her better and ideally would like to ask her out on a date sometime in the next couple of weeks, but she doesn't seem to be reciprocative to my approaches online. We have messaged on FB a few times, and she seems to be just as enthusiastic to be talking with me as she is in real life. None of the notorious "one-word responses"... Detailed responses. 

But she never messages me first :/ 

And also I was able to get her phone number, and what alarms me the most is that she has not responded to any of my texts approaching her for casual conversation related stuff (what are your interests, future plans? etc.). I have sent two, both appropriately timed so as to not seem desperate. And I know that she is receiving them because she recently texted me asking about something school-related, which she could not have done without receiving something from my number first... So that rules out the possibility of a tech problem being the culprit...

Any insight or ideas as to what could be going on? It kind of hurts me because I really thought we had a thing going, and I am really hesitant to try to make any more advances until she tosses the ball back :(

Can you summarize the given text in a few sentences?
<bot>: Getting really strange, mixed signals from my crush, should I accept that she isn't interested in me, or continue to pursue a relationship with her?
