Sharlee,
This is classic emotional abuse - making the woman feel worthless, like she can't do any better.
I expect your husband is feeling weak at the uncontrolable circumstances & the way he deals with it is by making you feel as though you're niot good enough. When actually HE'S the one that isn't good enough for you!
Even if you get through all this mess together, you'll NEVER forget the way he's behaved. You need to concentrate on getting you better right now. Respite would be good.
How can ou heal when he's bringing you down? Think of yourself.
You're in our thoughts.
