You are wrong.
1. Michael Schiavo NEVER made any such claim until AFTER the malpractice suits settled and Terri was awarded money for her rehabilitation (which Michael instead spent on legal fees to end her life).
2. Even IF Terri had ever made such a statement, at the time of her injury a feeding tube WAS NOT considered "extraordinary" life support under Florida law and therefore could not be removed.
3. As far as Michael being the "closest family member," Terri had conversations in the days before her accident in which she indicated that Michael was abusive and she was thinking about leaving him. Moreover, when someone abandons their spouse, moves in with a person of the opposite sex and has children with them, a normal assumption is that, regardless of legalities, the marriage is essentially over.
