So I hooked up with this really cute girl at a party a few weeks ago. We texted back and forth, with her starting the texting most of the time, but she kept standing me up so I just stopped talking to her since it was a waste of time. Since the start of this semester, she's started texting me again, and we hung out at a party and she introduced me to her friends from school and from her hometown who were visiting and ALL said "They've heard so much about me". I also heard later on that she's been talking about me (positively) to a lot of people in her dorm. Yet, she still keeps standing me up when I want to hang out. If anyone can guess what is going on here I'd really appreciate it.

she is probably not half as interested as you think

however since that mindset isn't going o help you assume she wants your cock and is just playing coy, I would make a bolder more alpha move on her when the time is right, sooner then later, ignore her until then. If that doesn't get compliance move on. Whatever you do, don't supplicate.
