Call his bluff. Make him seriously think about what it would mean if he divorced you for medical reasons. I am pretty sure you would take him to the cleaners financially. Don't appeal to his emotions, show him how it will cost half of his possessions, retirement, and a good chunk of his income.
Texas is a "Fair & Just" divorce state. That doesn't necessarily mean a 50/50 split. He may want to think before he opens his mouth again.

Screw him.
Get the surgery.
Lose the weight.
Divorce him.

Do you have that doctor's information? Do you know if they accepted Medicare plans in addition to self pay?

I'm self pay in Houston but I'm not using those particular doctors. They should be able to give you a cash price at your consultation. Mine went over all my options at that time. I can tell you that the cash price for my doc was $12,400 but reduced to $8,100 because they found a hiatal hernia, so my insurance will be subsidizing the surgery. However, there is a HUGE variance between doctors in Houston. Even down to what specific hospital you use. That was actually the biggest cost variance in my surgery.
