<human>: Can you summarize the given text in a few sentences?

Back Story: Over the summer, this girl(F17) approached me (M18) on Facebook, and we started talking a little bit. Nothing personal or anything, it was pretty much small talk. She gave me her numbe, and we talked for about two weeks. 

So I took advice from a friend(Who at the time, just wanted me all to herself and advised me against doing anything with her. I don't trust that friend anymore, and we are no longer friends.), and didn't go anywhere with this. Fast forward to now, and I catch her staring at me frequently. I'm sure she still likes me, but things are a bit awkward between us. 

The most interaction we have is making eye contact, quite frequently, at the lunch table. I'm thinking, I'll just start texting her again, and if that seems to go well, I'll ask her out at lunch or something. I was just wanting some input as to weather or not this seemed like a good idea.

(It isn't really a huge deal to me weather or not we go out, I just don't want to make a fool of myself.)
<bot>: Girl approaches me, and I don't act on it. Still catch her staring at me all the time, and want to ask her out. Good idea?
