I also agree with the two ladies, who gave you great advise.
BUT, I have to say, that every time I read about uncaring spouses ( there are way to many of them), it makes me very angry. Because we know, if the shoe was on the other foot, he would expect you to support him, right?
I thank my husband all the time, for being supportive, loving, understanding and helpful. His answer always is " that is what a real man does, for the woman he loves".
Hopefully your husband will change his tune, once you have a diagnosis.
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
