Hmm...sounds like you got yourself quite the dilemna.
I'm new to the pick-up artistry as well...but I might be able to make a suggestion
what you want to do is...wait another couple of days...and then text back saying something that will literally force her to have to reply or at least consider it...for example...you might want to say "Hey, I just saw your twin today, she looked exactly like you except her hair was fake
"...something funny, not necessarily what I said though. You may also want to try refering back to the night you two met. Recall something about her that you might be able to make fun of her about. For instance, if she drank a lot that night, you might want to say..."Hello binge drinker. What's up?". this is all based on advice I read somewhere...however I must say...if you've messaged her constantly and displayed any sort of neediness...you should quite possibly cut her off as a potential and move on to other women...a true pick up artist never dwells on one girl and has the ability to move on, stay confident and pick up more women....after all, practice makes perfect-Elijah
