its hard enough to have a life altering disease, without spousal issues on top of it. It sounds like your plate is full beyond measure, and I would demand a break for myself. You cant work on your marriage, or your partner till you work on yourself. Please, find the time, the love, the respect, and the space needed to work on just you. You are important enough, good enough, and worthy enough to be worked on first. Once you get yourself into a stable space, only then can and should you work on marriage or spouses or children. Make sure while you are working on you, he is working on himself. its harder to knock down a house with a strong foundation.

I wish much love and support for you. Hang in there.
