TITLE: [19M] Wondering what my next move should [19F]
POST: Background:
I recently started FB messaging a girl I used to have classes with in first semester of college. During the first semester she had a boyfriend. But they broke up and its been a couple months since its happened. When we first started talking again that was one of the first things that she told me.

More recent:
 We would talk every so often on FB. Out of the blue a couple days ago she gave me her number and told me to text her instead. So I did. We started talking some more and now we  have been meeting up at the school's library. She found out that I have started to workout and is all of a sudden working out now as well. Do you think this a coincidence or is something a foot?

I do like this girl, but Im nervous that I will do something to screw up or push her away. I also find that when I do talk to her I get nervous and run out of things to say..
TL;DR: 
Started talking to a girl again that I met in first semester. She Gave me her number, told me she is single. Found out I am working out and is now as well. Not sure how to proceed
