Really?
For such a small argument you want to file divorce papers?? This woman gave you two kids, and you want to throw her out?
What kind of human being are you. First ask yourself that. Then ask why you didn't get a better wife.
And to top it off, I dont care how arranged this was - this was YOUR decision to marry her. Now be responsible about it, and stay with the woman and work out your differences.
I am not hoping for it to happen but in the worst case scenario, I will not kick her out of the house and that is my promise to myself. I will move out if it come down to that level.
