To try and fill in some of the blanks so folks aren't doing it on their own:

My wife does not want to die. She is not contemplating suicide.
She is getting nutrition. Since my original post her intake by mouth has increased dramatically, but, is still short of ideal.

As to Charm's four items:
1. Her tube issues have nothing to do with the type, brand, style of g-tube, or the fact that she may be on one for a long time. All the formulas make her ill (ie: nausea, vomiting, diarrhea, etc.). This is a placement issue and there isn't an alternative location because this is the alternative location (Best location destroyed the first time).
2. We have blenders and food processors and she is taking by mouth what I eat, and we have meals together.
3. & 4. Her speech impediment is not caused by her teeth or jaw and she is seeing a speech therapist.

Right now the Dr's are not going to put her on hospice. They probably won't until it is too little too late. I know there is a good chance she will not reach her nutritional goal, and want to be prepared.
