Wow Vix, you do have a dilemma....the note is a good idea, it gets the subject out there for discussion.
I totally understand that you and your husband have made decisions together throughout your marriage, however, some decisions have to be made on your own.
I decided to get banded, came home and told my husband, he said" you don't have to do something that drastic, I love you the way you are" . I appreciated those words, but decided to go ahead with it for me and my health. He was fully supportive and took me to the appointments and to the hospital for surgery. He would not agree to having surgery out of province ( I live in Ontario, Canada), so proposing the OCC, was not an option. I told him that I would arrange to pay for it myself and we left it at that.
If you tell him how important this is to you and your health and that if need be, you will finance it yourself. You want him to support you, but if he cannot, you are going to do it anyway. If he truly loves you and wants to make you happy and healthy, he'll at least think about it.
Good luck with this, if you need anything at all, just ask!!
