I would not want my mother (my only remaining parent) interfering in my husband's decisions, even if he chose the worse (not the better) and decided to let me die.
For this reason shall a man leave his parents and cleave only to his wife.
What God hath put together let no man put asunder.
I would not want the bond between my husband and myself broken by a parent, even if I believed my husband was making a bad, even a sinful, decision.
Divorce, never. Turning over custody might be an option, but only with my husband's consent.
Just my view from the peanut gallery.
