<human>: I am a male (19) freshman in college, and I've never really been good with women. I have never had a girlfriend, but I am a fairly social person (though I don't go out to parties, as its simply not my scene.)

Early on in the year, I managed to meet a very nice girl that I thought would be "a good match" with me. We were doing some volunteer work and I got to talk to her a quite a bit. She seemed to have some interest in me, and before we all left I asked her for her number, and she gave it to me. The next day or two I started texting her, hoping to eventually ask her on a date, but after only a few texts the conversation died. I was way too nervous to talk to her again, and very shortly I felt like it was too late to talk to her much more. 

So, we never really talked since then, and just recently I was standing on the corner near a bus stop, and she was across the street walking to get on the bus. (I was running a fundraiser and couldn't really step away). I noticed that she and her friend kept laughing and looking my way, and to be honest she seemed quite nervous about noticing me. I may be making false assumptions, but I take it to mean she does have an interest in me despite not having talked to me in almost 8+ months. 

I realize that she very possibly has a boyfriend by now, as I've facebook creeped on her just enough to see a picture of her standing next to a guy whom I can easily assume is her boyfriend. I know it might not be worth it, but I still strongly feel like I should talk to her again and see if I can make anything out of it. So, my question here is this: Should I try talking to her again and ask her to meet somewhere to talk or should I move on?

Summarize the given text in a few sentences.
<bot>: I met a girl several months ago, only talked to her once shortly after that. Saw her again recently. Should I ask her out?
