That is a bummer. When I was diagnosed it was strange to see how people reacted. I have one friend/co-worker that doesn't want to hear anything about MS ever. It is very odd. I think it must be fear related. Talk to your wife about her fears. I share articles, news, updates with my husband and he is okay with it. Your wife sounds scared to me. Try not to take it personally. People deal with this sort of thing in all different ways. Good luck and know that here, there are people who can relate to what you are going through.
Love and prayers,
Ever stop to think, and forget to start again???
