I'll be honest man, this is pretty bad. The issue is that the wast majority of the conversation is about school work and boring topics. There's no tension, flirting, teasing, joking .... It's all boring logical talk. This is how 2 friends would talk if they're over 60 and not man to women. I recommend going through some of my LRs and observing the difference. Try to feel the difference in the vibe of how I interact with women.

I think if your real life game is anywhere similar to your textgame then the girl thought you asked her for her number in a friendly way so she gave it to you to be friends. That's the issue about not being clear about your intentions.

Your textgame should be more or less congruent to how you are in real life. When I meet chicks in my date-to-day life I'm fun, flirty, and make some sexual jokes. Then when I go to invite chicks straight to my place over text is a lot more congruent. I seldom sext girls, because it just wouldn't be that congruent with my personality. The point I'm trying to make is that if you're super friendly in real life and have a hard time communicating intent then you can't go and do a complete 180 over text. But, you can nudge the interaction in the right direction. So, maybe for you sexting and straight to the house dates are too much at this poitn but meeting at a bar is just congruent enough to work. Hope this helps man, let me know if you have any questions.
