It's one thing to be stubborn, it's quite another to be stupid.
Since your husband seems to have an overinflated image of his masculinity (too bad you are not local so I could drive over and tell him in person and dare him to do something about it - after a fight, guys bond and I wouldn't hurt him too much), sometimes, like judo, that can be used against him. My suggestion is to smile and say how you have read here on OCF that some men find it just too difficult to force down Ensure, or other drinks and you understand that not everybody can do that. The other option is to say that some men just don't want to bother with all that liquid sissy drinks so they get a PEG tube right into their stomach. What's a little hole to a real man, right? I don't know what would work best for him.
You have tried reason and facts without success.
Seriously, doesn't he have a brother or father or buddy who can talk some sense into him. If he cannot stomach the drinks, then he had to have a PEG tube.
I'm so sorry he is being so mean to you when all you are trying to do here is keep him alive.
