When you told her that in your state, a spouse doesn't get alimony in the case of an A, were you speaking from knowledge or were you just spouting something?
I can see now why she is so paranoid about this. But if you weren't speaking from knowledge then if I were you, I would admit you said it in anger and that you don't know the law and that if/when you get to the point of needing an attorney you will discuss it with them at that time.
