Hey guys,
I've been lurking a while here but finally registered! This site has a wealth of information and I have benefited quite a bit from it.
However, now I do come with an issue that I'm hoping you guys can help me with.
There's this girl in one of my classes at college that we met on the first day (introduced by a friend of mine) and us three agreed to help each other with homework.
Well, usually it's just the two of us (girl and I) for a good hour and a half working on homework until my buddy joins us after his class is out. Jane (lets call her that, shall we?

) and I would usually grab some food before we start our work and just talk. Even after we're done for the night, I would walk her back to her bus stop, hug, and part ways. Right outta the movies, right?
Anyways, all this started about five weeks back and I really did think that we could have *something* going (she did ask me for a fire department shirt as she thought those were "really cool"...).
So...last Thursday, I asked her (or texted for that matter) whether she wanted to grab some lunch. Bless her heart; no response. And she usually returns texts in seconds.
Next day, she texts me with a nice, long, lovely, message stating that she had to go to the doctor and wouldn't be in class. There was no reason for me to not believe her, as she was sick for the past few days. And isn't it a bit extreme to skip class to avoid a guy?
So yesterday, after walking her back, I asked her whether she wanted to grab some lunch today. A quite enthusiastic "Yeah!" was spewed and she told me to text her tomorrow and we'll figure out a time and place.
I cheerfully sent a text around noon-ish and since then, haven't gotten a reply...she's been quite active on Facebook, so I know that she isn't hospitalized or lying in a ditch somewhere or too busy to not text. At least give me something! Lie to me if you have to!
Thing is, I see her tomorrow...how should I approach this? I really don't want to make this awkward for the both of us (I'm sure she's feeling the same). She's a nice girl that I wouldn't want to lose as a friend even if things romantically may not work out.
Thanks for putting up with me,
-B
Oh, and forgot to add...I'm quite surprised to find myself posting this. Entering a burning structure; I won't bat an eyebrow. Venturing into relationships and all...oh boy. Interesting how life works, eh?
