Hello, so here is the situation:

There was a girl I really had a crush on in a large class, but I never got the chance to say hi and introduce myself. So over the summer (after much much thinking of how creepy this might come across as and whether or not I should even do it), I send her a message on facebook saying how I always wanted to say hi, but never got the chance. She responded very well and she even sent me a friend request. So over the summer we chatted a few times and she seemed quite into it, so I knew she wasn't too creeped out by the situation, and it seemed she might have even kinda liked me. And then right before school started I messaged her again saying hi, she responded well asking how I was, and I replied and asked her how she was, and no response. It's been a week and still nothing.

And now school has started, and I saw her on campus, on a path where there are a bunch of students walking to class. And it was one of those incredibly awkward walking towards each other instances. I was going to do the typical "look down until she is close enough to look up and say hi" thing, since I didn't want it to seem like I was staring her down. I am pretty sure she saw me, and just as we got closer. Bam. She disappears through the first door she finds. Whether or not she was running away from me I do not know, but it seemed pretty obvious to me.

Why though? Does she really think I am a creep? I sure do feel like one right now. I am now terrified of running into her on campus again, just because I feel like a creep now, and I don't want to seem like I am pursuing her. The last thing I would want is to appear as someone that should be avoided. I wouldn't dare message her again on facebook now. I just feel like she thinks I am some weirdo who is looking for her. I don't know what to do if I run into her on campus again...
