They pull of for a reason, and you are probably doing something wrong.
If they after few days say "lets be friends" then it's b/c you don't elicit sexual tension enough. You know, guys hear "lets be friends" only when they act as friends, but those that make sexual tension, tease, lead, make them horny in every way possible wont hear that line. Work on that buddy. And don't ask them out, TELL THEM!
Tell something like, im not a fan of facebook chatting... meet me at xy tomorrow so we can talk like people face to face and have some fun... Show some leadeship, confidence and dont ask. Tease them if they are scared.
If they don't answer, move on buddy

. Fuck'em, theres plenty of fish in the sea.
This. I mean, there are some freak occurences, but overall, you probably need to be more sexual in your game. Women are very fond of words, in fact words make them hornier than pictures. Simply talking about sex with her, if you do it right (Don't necessarily start asking her for all her experiences, and don't get into the specifics of boyfriends or whatever), will make her imagine having sex with you, then she'll start asking herself tons of questions like: What would he be like? Is he good? Am I attracted to him? etc etc...
From there, as long as you keep her chasing you, and keep her interest while making an emotional connection, the answers to those questions will be positive.
