Sorry man,I think you are in some deep s**t here. Wives are not supposed to behave like that.
How about you call her bluff. Next time she throws a tantrum,why not throw an even bigger one. Attack her (not physically) so viciously,such that she gets thrown offguard. That way,she will learn to pick her fights.
After that leave,on one of your foreign trips without telling her where you are going.
See what happens the next time you return,without any new clothes for her,let her buy herself her own clothes.
I guess if you can't win with facts,you can always pen bile-laced,xenophobic rants to distract everyone.
