Well, I know my husband is adamant. He has told me over and over. In fact, he's told me just to give him a bottle of vodka and a gun! I am clear as to what his wishes are and would never allow someone, even if they're well-meaning, to subvert those wishes.
Great, then you're situation is very different from Terri's. Even Michael doesn't say she "told him over and over again." He didn't even mention the one casual remark she supposedly made, until years after she was incapacitated. The bottom line is that there's isn't clear and convincing evidence that she'd want to be put down. Greer was exposing his incompetence - or some ideological agenda (I believe it's the incompetence of a hack local judge/former county commissioner) - in basing a death order on such scanty evidence. Florida law says where the evidence isn't clear and compelling, you don't withdraw the tube. He blew it, and he's as stubborn as he is stupid (as a judge), so he won't back down. The appellate courts don't review the facts, so they can't be any help.
Fortunately, the congressional bill would let a federal judge review the whole thing - de novo - as if new, from the ground up. No court has taken a second look at the facts that Greer based his judgment on. Now that that might happen, we may soon see how very wrong - and stupid - he was/is.
