Girls don't talk to give you information or tell it as it is: they talk to make people do stuff. It goes like, "If I say xyz, then s/he'll do that, which is what I want. So I will go ahead and say xyz."
Once you understand that, and also that feelings mean more than **anything else** to a girl, everything else comes kinda easily. (Sort of.)
Make a girl feel good and the girl will want to understand you, not the other way around :)
