GIRLS...PLEASE HELP!?

I'm 18 years old, a freshman in college. My grandma's best friend has a realllllly cute granddaughter and she's applying to the same college that I'm at, so our grandmothers had her in touch with me and I gave her some advice on the application, essays, interviews, etc... She came up to visit and stayed with me for the weekend- that was the first time I met her in person...we had a great time, she loved the campus, and this college is now her top choice. She applied early decision and got deferred, meaning she won't know until April whether she's in or not. In the short time that I was with her, I felt a really strong attraction to her- both her looks and personality seemed like everything I could want in a girl. So now, I'm back at school and we're 6 hours apart from each other...We've texted a few times since then briefly about stuff related to college, but sometimes we'll just have like a fun conversation after starting by talking about colleges, and she'll use lots of smileys, exclamation points, and extra letters (likee thissss!)......What should I do now about her? I really miss her but I can't exactly make plans to hang out while we're this far apart. Also, I don't want to like annoy her or creep her out if I text her more frequently, so I'm not sure how to go about this.
