Is she really interested? (Part 2)

It's impossible to tell, my friend. (I read both questions)

How long has it been since you called and didn't hear from her? I'd say give it a few days or a week WITHOUT texting or calling, to see if she gets back to you. (If she's really interested, she should get back before long). After this, you can try maybe one more time to establish contact; if she's still noncommital, I'd say move on to a girl who likes you and won't play games.

I'm not saying she IS playing games, but maybe she's fallen into this pattern out of habit. Most super-attractive girls are used to needy guys who call them all the time and are desperate to make contact; when you show indifference, hold back and make her chase YOU, you set yourself apart and become more interesting and attractive. The idea is, you don't want to give yourself away on a silver platter--you want to make her work for your affection and make her think, "I think he MIGHT like me, but does he?" When you demonstrate this high value by just being relaxed about things, she realizes that you don't need her, and she must work to keep you around.

Just relax and be cool about everything, and check out other girls in the meantime. Best of luck man.
