I've had a similar experience. To see the details, look at my past posts.
In my humble opinion, what works best when you don't have a chance to show your value directly and texts / fb kill all the attraction is to disappear at all.
this worked great for me, but mind, it took me almost two months to take her out after a kiss close in a club...
out of these two months, I spent 3 weeks in silence, then wrote her again being very direct. she proposed a date and we finally met
(most people on this forum will now argue that HER proposing a date means I'm weak and blah blah blah... most girls I talked to, anyway, told me how unreasonable it is when they get proposed a time and a place, and how it makes them feel pressured. anyway, this is just a detail, and it may work out very differently for you)
anyway, good luck!
