I agree with Izzy, I would also say that if you are in a relationship where there is 'proper communication' in as much as you can talk to her about it and come to an arrangement where 'good behaviour' is rewarded. 

Did you ever have temper tantrums as a child?  What did she do to deal with it???  Good luck

Like with children's tantrums, you have to rufuse to give the tantrum itself power. If you ignore the tantrum, pretty soon the person will realize that he/she has to resort to some other behavior to get the result that he/she is used to getting.
