anothercasualty...I just have to ask you...as your wife was spewing this fantasy divorce scnario, what were you doing? Just listening and trying not to puke?
Because the thing is....as you are sitting there just even listening to her spew this, you are tacitly agreeing to it, in her mind.
If you have self-respect, you will hold your hand up in her face within the first 30 seconds of spew and say "just hold it right there...that is NOT how our divorce will be so you may as well save your breath". Then let her fuss, cry, try to argue, or whatever she wants to do, but don't even address further.
The fact that you even heard her out has now put you in a position of weakness, and she thinks you thoroughly agree with her every word. Sorry...you kinda blew this one.
