I am sure you have heard this before but alot of times if a man can't fix it, they ignore it.
My DH is the same way. Even though I do have MS on days that I am really tired or feeling crappy he will say things like. "If you got up and did something maybe you wouldn't feel so bad"
He was in denial for a long time and sometimes he still is, so I do know what you are going through.
It does sound as though you DH might be coming around! It makes things a lot easier when you get that support.
Good luck and take care of yourself
