Should Martin die or not?

It' s a difficult decision for us as a family member to face this problem. If let Martin live, we must bear such a heavy burden because of the high cost. However, if let him die, we don't have the heart to put away the machines which he kept alive on. So what should we do? It's really hard to deal with this problem. I think if I am Martin wife, I will do as much as possible to prolong Martin's life untill we don't any money. Because if he is alive, I have the hope to support and maintain the whole family.What's more, I still have a husband and the family is complete. Once I have no money and can't afford the medical cost, I have no guilty and regret because I have tried my best. I think my husband can understand me.
