That's a very interesting fantasy you've described, but it has nothing to do with what happened to Terri. Maybe you should take the time to read up on her situation.
No abuse, no "conservative" believes that Terri told him she wouldn't want to be kept alive in a PVS, but they do believe Terri's friends who say she was getting a divorce even though Terri never talked to a lawyer or filed any paperwork, and even though MS was on good terms with Terri's family for the first several years of the PVS. No "conservative" in this thread at least accepts a marriage contract as being sufficient for a husband to make that decision. It must be augmented with a living will.
