Here's the back story to this whole saga.
I've liked this girl a while, she goes to various same parties as me and I am good friends with a lot of her friends but I've never really spoken to her (danced with her a bit, idle chit-chat etc.) when yesterday a friend went on my phone and basically destroyed it, commenting weird sh*t on various different Instagram pics and facebook posts which happened to include her profile.
Anyway, I sent her a quick "sorry for that comment last night, It wasn't me on my account" (It was fairly obvious that it wasn't me) and that has got us talking all through the day on Facebook.
The last message I got was in the early hours of the morning (0500) as she is going on holiday with a mate. Last night (2100 or so) I suggested we texted as I have no data to Facebook message while I'm out of the house, and obviously it worked as I now have her number.
My question is, what do I do? I have her number so I could theoretically text her but I don't want to look desperate and it is unlikely she'll reply often if she's on holiday, but I obviously want to maintain interest
