Maywalk You have to decide what is best for you; having that operation would be a big thing and would it help with your quality of life? If you have decided 'no' then you have made the right decision for you.
I am sure that you made the right decision for your husband too, in the knowledge that he would have been well cared for and you were not able to do that.
It is good that you have such a supportive family and I wish you joy with your new great-grandson 

Are you in your forever house?
Retiring and living frugally in money from downsizing after years of stress
