Why do I always think girls like me when they don't?

qstoffe
I often get the impression that girls like me and that they have that subtle flirting going on with me. During this build up of "signs" I get more and more certain that the girl like me. But every time actually make something concrete out of it, like ask her out, they always turn me down. Some do it politely, others just flat out ignore me.

Is this a common scenario? Or am I completely incompetent at reading girls signs of interest/disinterest?

What are som good indicators of interest vs disinterest?
