Attraction is hard to build on facebook, or txting. You gotta meet up with her in person to really pull shit off.
Option 1: What I think that you should do is send her a few cocky funny txts so she has no choice but to have a higher opinion of you, then invite her to something thats too fun to pass up...(a good party, group game of minigolf whatever...). Also when you invite her dont make it look like she is special when she's getting invited. Even consider starting a txt to her with (mass txt) so she thinks you are txting lots of other ppl too (actually txt other ppl too btw. you are trying to get people to some fun event).
Option 2: Just be direct. Text her I think you're cute lets hang out and she will either be really impressed or creeped out. Its worth a try.
Good luck dude.
