All I'll say is the very first time she does something you really dont approve of let her damn well know it. Our initial impressions tend to be the strongest so If she gets away with something once, she knows she can do it at all the times if she's persistant enough.

Go Pavlov on her her ass. Chances she'll be testing you seeing what your reactions are, Dont fall prey. Your under no obligation at all to defend yourself for anything. Simply offer no reaction. If you go on the defensive then you've given her actions validation. Like Jaz says calibrate dont be doing in a way that you'r coming off as being in a 'mood' with her.

The opposit of love isnt Hate its indifference.

Same goes the opposit way, if she does some you like then tell her she's a girl, soon enough her unconscious will get the message and she'll behave herself.

Take my advice coming from someone who's been in full on Sub Dom realtionships before. Its always the strong confident self assured women who are the first to submit. They have more to lose from giving away control so they will damm well test you to see if your good enough. Once they realise you cant be manipulated they will just go along for the ride.
