My husband and I made that choice when he was given a cancer life sentence. We did everything possible to keep him alive naturally until he went into a coma. No regrets.
We just turned it over to God, and He made all of the arrangements. Again no regrets.
Y’all did the right thing.God doesn’t require we suffer with a terminal illness if there is no hope around the horizon.
If it WAS the wrong decision,I will let God judge me and ONLY God.
