Hey Cobra (are you back from vacation, or at some internet cafe, or on your Blackberry?)
Your observation may be correct. I have as much as told my wife (usually in the midst of an argument) that the only reason I am still married to her is because of DD5.
What you suggest may indeed be the only way to "rattle the cage" enough to get her attention.
The chance that she'd just agree to cut and run, though, seems more likely to me than her actually putting in the effort to see that my needs or views might be valid.
