About a week ago I went out with my friends, there were also a couple girls who came with them, and I really hit it off with one of them, she was obviously into me, though I'm not sure if she 

It's been days since then, and I haven't even added her on Facebook, because I thought we live kinda far away, so it's pointless because nothing's going to happen, but I still think on a daily basis about if I should add her and talk to her, so I think I'll do that tonight, because I know the worst that could happen is that nothing happens, and that's better than every day thinking about what to do.

The problem is that I'm really low-profile on Facebook, I never like, post or share anything, I never add new friends (I only confirm those who add me), and I only talk to my 5-6 of my best friends, and really rarely I talk to some other friends (or more like pals), so I really don't know how to talk to an almost complete stranger online, even though I can talk to anyone IRL when we're out at night.

Any tips on how should I approach her? It's only the initial part that I'm "afraid of", once we hit it off online too I'll know how to continue, but I don't know where to start, especially that it's almost been a week since we met.

So I'll add her, she'll probably confirm, and I'll write her a message, saying what?
<bot>: Met a girl who was obviously into me a week ago, I'll only add her on FB now, I'm good at talking IRL, but I'm shit at it online, how do I begin the conversation?
