Well i am going to offer a different opinion. I am BiPolar and if it was not for the encouragement of my husband I would not be where I am today. He did not accept the fact that I wanted to lay in bed, and go on disability. He shouldered the burden of many things, and then told me to get up. He said the world needed what I had to offer, and that I was responsible for my own mental health. In the most caring way he could.
I sincerely hope you do not take this as a criticism as you are a wonderful and caring wife. But spouses, in an effort to try to make things easy for a bipolar spouse can enable them to focus on their illness and not take responsibility for their existence.
Have an open dialogue, and let him know how you feel.
