Lots of the hospital drama could have been avoided. I understand you were scared and unprepared to have to endure such an experience but learn from your mistakes.
If you are not living with your W and your marriage is not stable you should have a Health Care Proxy. If you Google your state and "health care proxy form" the document should be free to download. It's a detailed document stating your wishes if you are unable to make medical decisions or if you need assistance during times of medical emergencies. It also removes your W from the equation.
Fill out the form and have your attny or a notary sign it. Shrink it down and put it in your wallet. Give a copy to all of your health care providers. Anybody going through a separation/divorce should have one.
Had you had something put in place you would not have had to scramble around and make calls and put people on "do not call lists". The Health Care Proxy document would have all of that spelled out.
My sister is my Health Care Proxy and my mom is my secondary Proxy. It saves you from lots of drama and stress should a medical situation come up during a divorce/separation.
