<human>: Give me the gist of the text in a nutshell

I was in the library Tuesday night and saw a stunning girl and I knew I couldn't let her go without at least trying to get her number. After and hour of hyping myself up I got the courage to ask her for her number and it worked. I waited until noon the next day to text her and unfortunately we didn't have too deep of a conversation ( I'm really awkward and bad at talking to girls) and she took about an hour between each text. We talked about our majors and some interests then a lot about music. I didn't text back to one of her last texts because I couldn't think of something to say and forgot to text back. Now it's Thirsday evening and we haven't talked yet today. 

Should I text her and start a conversation or is this just a sign that she isn't interested anymore? I don't want to seem like a creepy stalker by texting her all the time. Or is she just shy and waiting for me to start a conversation which is why she takes so damn long to text back? This is my very first time getting a girls number so I have no idea what to do. Even if she isn't interested in me anymore I'm just proud of myself that I was able to ask a field for her number for the first time.
