Someone above recommended push pull. I'm not sure what that means.
Push / Pull - Give her a little of something she wants, then take it away, leaving her wanting more. When you give it back to her again, she really wants it, and then you can push further, then take away again. Rinse and repeat until she's begging for your cock.
In this situation, it sounds like you started acting needy, seeing her too often, texting or calling too much, and generally not being aloof and disinterested enough. The best thing to do is to gauge her investment and always give a little LESS than she is. The simple technique that underlies this method is the 2/3rds rule. Never give her more than 2 texts / calls for every 3 she gives you. You're keeping interest and not completely cutting her out, but you're making her invest in you more than you're investing in her. (On an iPhone, you can scroll through your past text exchanges with girls really easily - when I do this, I find the interactions that went smoothly I often used the 2/3rd rule almost perfectly.)
I think your situation calls for a freeze out for 2/3 days. Give her the gift of missing you, and see if she re-engages. Take things from there, acknowledge you guys have fun together, but don't VERBALISE stuff. Talking about where your relationship is going is NOT hot. Just enjoy your time together and leave that stuff unsaid.
