Confused guy needs advice on confusing girl!?

[Pendragon]

After being invited to the same event we chatted and were a bit sarcastic to each other last week and ended by her going to bed and saying chat soon. I never followed up that conversation.

Then today she went through my facebook and "liked" loads of posts followed by a post saying " i liked loads of your stuff, just cause i could " We chatted randomly for a bit on the post and then she finished with "well thanks to you my phone battery is about to die, so ill say good night and see you at the event" . This isnt for a couple of weeks yet.

I'm not sure what to make of her recent actions or whether to take the chance and drop her a message in a couple days out the blue like she did me?

She's flirting with you dude, do the same thing back to her, just very subtly. When things get really heated (in a good way ) ask her out hope I helped
