I agree with Brandi as well however I feel that what Chris was saying was that she needs to leave to take care of herself (go to a shelter, go to a food kitchen, etc.), becuase if she doesn't eat then I would say her most basic need to be filled at the moment is simply survival. If after you leave he gets his act together and you believe that he has seriously reconsidered things then you could try again at that point, assuming it is something that you want to do.

Either way, I'm sure there is more going on here than meets the eye and this is only one incident in the last XX years of your lives together. I can only give a perspective on this one thing and it is obviously out of context.
