Her so called "Husband" has long since remarried. He can't possibly be her husband anymore, or am I wrong?

Confused here. The issue of life and death is a delicate one.

I am terrible with issues pertaining to this sort of thing when I do not understand the whys. It is said that this man, "her husband" refused therapy for Terri years back and remarried and started his life with another woman and long since has had children with another woman yet can still make decisions for Terri. What is this? Isn't it illegal to have TWO wives? I thought it was. In all honesty, this man has nothing to do with this woman other than stand to get a very large sum of monies if she should die and he needs it badly in order to pay off the $600,000 he owes to attornies. I guess he figured she would die sooner if he refused any kind of therapy. What was he afraid of, that she would get better? There is something behind this man's behavior and if no one can actually see it, then obviously we are trying not to. We are blinded by the fact that money is an issue and that she must be let go so that others can live. I appreciate that. That's not the issue. The issue is, who should be deciding her fate. The family, I say, should. If my husband remarried and started his own life with someone else, than he forfeited his rights to anything having to do with me. I am so confused. Is it because they chose life that the law gave him the right to choose? That is honestly something....but why did the therapy stop? Why was it refulsed? Was it because there was no hope? Why did the law intervene to stop that therapy? That was years back? Why isn't anyone asking these questions? If it were me in her shoes, I'd hoped that everything possible would have been done THERAPY and all. It's so very SAD that this man controlled her life in that manner.
