BigTen, i don't blame you for being angry and stuff cause i've been reading this and there are few posts where people take a dig at ya. But try thinking calmly, control your frustration and read other people's reasoning. Illusion is right in the sense that you should see things from other people's perspective. Imagine yourself in other people's shoes when this problem arises before letting all the swearing and cuss out.

Now for your problem, before you truely know a girl, its natural for her to be shy and awkward when both of you hardly knew each other. Give her some time and keep in contact more frequently. She'll open up to you slowly~
