Labkid, my own situation has lots of commonalities to yours. My heart goes out to you and your husband.
My husband had bent his career path for me before. This time, I really don't want to ask him again.
He wouldn't / won't be doing it
for you, he'll be doing it for your son and for the sake of your family.
Everything in our lives have changed in the last few years to accommodate our child's special needs. It's not easy, but we can get through it (most of the time!) by focusing on our child's needs rather than our previous expectations of what our lives should be.
That's the bad news. The good news is that what will actually bring you happiness is rarely what you thought would bring you happiness ... so you and/or your husband may not be giving up as much as it seems at first.
Ditto to poiuy and mignon's suggestions that you consider state programs, health insurance provisions, availability of services, etc. as major factors in your job searches. And as much as I hate to pick the nits on larryc's well-meaning advice, I have to caution you that not all decent people will understand. Yes, they may have sympathy up to a point, but it is hard for most people to understand just what challenges your son's needs do and will pose for your family.
Please PM me if you would like to chat, or if it would be helpful for you to hear more about my experience the last few years.
