It might be true that whether Michael has someone else is none of our business. However, don't you think there would be some kind of a conflict of interest there? What kind of a woman would take up with a man and have 2 children by him, knowing he has a wife in Terri's state. I just think he has lost his objectivity here. Having her die, might be an answer to his dilemma. Many men have killed their wives for less reason.
I have a cyber friend going through the same thing, just not a medical prob going on there.
