Hi there. This is going to be a long road for the both of you. The first key is communication. Open up to him. However, men usually tend to feel like we're blaming them for stuff, even when we're just making comments (not that women don't do that either), especially when they're feeling bad about themselves. Your husband has a lot going on. He may be depressed due to the diabetes. Some people don't take the news that they will depend on medication, restricted diet, for the rest of their lives. Men want to be our hero, invincible, our Wall, so to speak. Some men (and women) feel like they're not whole, when they develop a medical issues such as this, or even severe injuries (like my hubby has been going thru for almost a year). So, depression, and/or feeling "Less-Than", may also be a culprit. I understand his desire for not taking any more pills, however, he has to also be totally honest with his doctor. Most men don't want to admit their little soldier isn't at attention as much as he use to, due to pride and embarrassment, but, his doctor will also want him to be as functional as possible, and also help in maintaining the marriage bed. He may be able to try a new sort of medication to help control the diabetes, that has less side-effects. He has to also communicate with YOU. Encourage him to open up. How's he feeling about all of this? Assure him that this is NOT his fault, and that you really do understand, and that you want him to know that you are willing to help him, but he also has to be willing to help himself. Best wishes!
