Perhaps this has been answered. . .but you are mixing your issues here. Terri had no written Will. . .the 'State' will respedt your wife's decision - if she puts it in writing ie 'get a Will'. Sign a 'Living Will, as well. . .
This actually leads to my central point of departure from the Terri supporters. My wife and I don't have a living will. We have a Christian marriage covenant, which should be enough. I trust her to make the decisions for me, and she trusts me to make them for her. But that isn't enough for the Terri crowd. They want the government involved.
I keep bringing up the living will because *most* supporters are in favor of having feeding tubes removed if that is what the person wanted, they just don't trust Michael. Maybe they are right not to trust him, but without evidence that amounts to destroying the bonds of marriage.
