Good for you! I'm so happy that he is finally believing you. I think a woman just knows when there is something wrong with their body.
It took me 2 years to get a diagnosis but I knew from the beginning it was MS.
My ex thought it was all in my head the whole time...until I told him I wanted a divorce. Then he "believed" me...yah right.
I'm glad that he is excepting of the idea now and is willing to support you. And having a sense of humor is the best thing. My doc told me the marriages that make it are the ones that can laugh at themselves
Best of luck to you
