• 1. Always look her in the eye while you imagine that you're fucking her brains out. The more detailed and graphic your imagination; the better. Warped Mindless' eyefuck routine will make your pupils dilate and pump up your hormonal levels which will make her very sexually attracted to you. Women are very emotional creatures rather than very logical ones. When she says she's not yet ready for a relationship, that's not set in stone when she feels horny around you.
  
  2. Cut back on the neediness. Game other girls while you're gaming her. Non-neediness increases your attractiveness as a man.

i see but how can i get her horny for me

Right now, you're the person who needs her more than she needs you; and a relationship like that will never work. Girls only chase what they can't have, you're waiting on the sidelines for a decision. Even if hypothetically she does accept your proposal because she thinks it'll be good for her, your relationship will have lackluster passion and will only remind her of what she misses about her ex.

You're supposed to communicate challenge to a girl, how are you doing that when you're texting her 20 minutes after you ask her out?

Never judge a girl by her words, only by her actions. You fucked up the moment you thought "oh she likes me because she said she likes me." Her saying it doesn't mean anything. Does she want to be your girlfriend? Do you guys have secks? Do you do anything? She doesn't like you. She likes the attention you give her and is using you as a surrogate boyfriend to cushion her ego from getting dumped by the guy she really wants. She is saying stuff like "You're amazing" to keep you hooked onto her approval, you are in a qualifying mentality.

All this being said, you're not out of hope. Granted you have a bit of a bond with her, you can segue into attraction by push/pulling and gaming other girls. A girl wants a guy with value; someone who OTHER GIRLS want, someone willing to dump her, someone she can capitulate to.
