Hi Greta,
I'm sorry your brother is the way that he is... But you're fabulous.

Sorry that MS seems to be running in your family.
That being said, I think you and your DH would be fabulous parents and hope you can have a baby. The treatment for MS has advanced so much, and you've done very well with it so far not having any attacks and such.
Whatever happens, I wish you the best, and try not to fret over your NSDB (not so dear brother). Sometimes I think there's one in every family.
