My diabetologist kept suggestion the surgery and gave me the info for the clinic. I went home and told my partner about it. I also told him that I didn't know yet if I'd do it, but I'd make an appointment for a consultation at the clinic.
The night before I left we had a long talk about it, he had a bunch of questions that I could answer already because I hate not being thoroughly informed to know what I need to ask the doctors. He said to me that this is my body and I should do what feels right for me. He loves me for me and will support me either way. I think the thing that made me realize how serious it is was when he said: "I want to grow old with you, any way you need to get there is worth seriously thinking about."
He's been supportive all the way, he reminds me of getting used to new habits like eating slowly, chewing more, not drinking during eating, as a preparation for post-OP but also because it's healthier. He was the very first I told about because this change will be something we both have to be in for. I can't do it without him having my back. Well, I could but it would be a LOT harder.
My parents know and my friends know. I wrote a blog about it, so my readers know too. Grabbing support where ever you can get it, right?
So talk with your husband, if writing a letter is easier for you than vocally talking, do that. Sometimes it's easier to do that, to be able to sort out what is going on in your mind and to structure your arguments. In the end, it is YOUR body. His support would be fantastic. He does want you around for a long time after all, right?
You can do it, keep at it!
