I know women generally try to avoid being direct and would rather give out signals... whether its to invite someone over or to hint them to go away.

Is it better to trust your instincts and go away if you see she's not super into it or should you just keep going until she explicitly tells you off? Sometimes you get into grey areas where you don't know which way she's leaning and its super confusing to deal with. Anyone here pushed past disinterested behavior and actually got somewhere?
