Steve,
of course I can't tell you what to do, but I think there's something to learn out of this experience so far.
Maybe it is to find new ways to connect to your family members except though shared food. I also believe that you should and could attend family meals in some way without eating the same things your loved ones do (you did while eating raw, didn't you?). And you already wrote about usine a shared meal as a way to connect with people to be something common, but no "natural law", so to say. Can you as a family find new ways to share your life with each other?
Maybe it is that you are too much out of sync and should stop - not only I did recognize that your posts lost more and more of the passion they used to express - although "Share Your Shame" did make a good point
Since you can't stop the feast with a snap of your fingers, I say you might at least continue another week to end the first 30 days, and then decide.
And I say you should discuss this thing with your family, since this is something that influences all of you. Are Erin and the kids feeling the same? Are there ways to solve the problems other than breaking the feast? Get out of your cave, and get a life *d&r*
Decide well...
