Sorry you're feeling bad about it brotherdan. You were just trying to diffuse the situation. Perhaps you can mention your point of view the next time it arises?
When I told my husband there was no way I would refuse a blood transfusion for our child based on one scripture he freaked out and couldn't handle it. So maybe it's a good thing you didn't press it at this time.
I told our doctor that I recinded my decision on the 'no blood' policy for myself and our child, and the doctor made a note of it. I told the doctor that my husband wasn't in agreement and I didn't want him to know about it and he was ok with that and reassured me that the doctors will give a child blood even if the parents disagree.
I hope you're never in a situation where you need to deal with this issue. Or if you are, that your wife will change her mind.
