because my children and i are covered under my h both for medical and financial support this is not a question I was ever faced with, BUT I would not recomend you do anything as rash as making such changes.
if you are feeling like the "good guy" by still providing in this manner for your w. stop don't think you are doing it for your w think you are doing it for your d, you want her to have a healthy mom and therefore providing mom with health coverage is a good idea. if however you'd like to add d to your life insurance policy that may not be a bad idea, not because of the current sit but because you want your d to appear on your policy as a benificiary.

and hey it's not a bad thing if you are realizing that you WILL be ok with or without w, it is a healthy thing.... you are realizing that your happiness does not depend on another being part of your life it depends on you and that is what detachment is all about.
