Girls, She didn't accept my friend request. Why?

So I've liked this girl for a while now and I'm pretty certain she likes me back. We've never actually spoken but the signs the tells me she likes me are:
She looks and makes eye contact with me constantly
She's always be around the same place I am
I've overheard her talk to her friend about me.

uni is over now, and the likelihood of seeing her again is low. So I decided to make a social media account and send a request, so we could talk. However it's been a couple days now and she's not responded to the request. I know she's been on, because she's changed her profile pic (couple hours after I sent the request).

What's my next step? Move on, wait, or send her a message?
