I think its not too late and you can always turn around. But why did you not arrange meet? Do you live in the same town as her? And has she got an addiction to theme parks? Call her, say that you might go and try to get her to convince you go. She may be asking you to bring some friends, because she hopes you turn up with some hot friends. So take a female friend with you, she probably wont expect that.
When you meet go through the phases as you did before, but you should take things further this time.

i havent responded yet. ill call her right now.
thanks

That explains why you did'nt meet her. Yeah dont answer phone messages. She must like you if she's invested this much in you. Is she the one who usually text's you first, its easy to tell their intrest by the amount of effort they put in. Just wait a short while now before making contact, you may want have a brief text chat first then tell her you're gonna call her after like 3 texts. Some girls get shy, since you dont normally talk to you on the phone.
But make sure you're also gaming other girls aswell.

we both text first about the same amount of times,but i think i text first to her more.i havent used any negs should i use some?

Personally i dont like to leave answer phone messages and i know people agree with me.
Im not sure how to explain it, you could say it can come across as needy, and it also puts her in control. Then if you call again after the message it shows how much you value her, needy and you're not controlling the frame. Also on the answer machine you've got to leave some stupid message like 'hello its me, please call me...'. And that aint cool. Best just to leave it and call again another time or wait for her to call

Only use a neg if she is a high vaule girl, and/or see's herself as having high vaule, and if she's higher vaule than you. Some say you should only neg 9 and 10's, but everybody rates them differently, and how does she rate herself, she maybe a 7 and she herself as a ten, and vice verser.
So stay away from negging some girls and just stick with the false-disqualifiers, you could still use a light neg though like 'are those nails real' or something.
Save the negs for when you meet, but be careful with them.

To be honest i've totally lost track of this thread, i've been replying to other guys threads too.

But here's a little bit of advice for you:

Don't be affraid to make mistakes, you'll learn just as much from mistakes as you will success. So just go with it and see what happens. Experiment sometimes, and dont put too much importance on one girl, if it doesn't go well with one, there's always another. If you just go out and have fun and not care so much what happens, it just might help your game.
