dear 49,
welcome to NT. i'm so glad you found us.

i'm not married but it may be that your dh is scared for both your futures.
men sort of feel they need to solve problems and i bet he feels like he can't do that. so he has no control. that's a scary feeling.

i found that truly dealing with 1 day at a time works for me. 1 test at a time etc. no one can predict the future, even healthy people. having MS isn't a death sentence. most people with MS lead independent, active lives.

i had to make some adjustments in my daily living, like using a cane. but i'm independent and drive and go places and have friends. i have to pace my energy and can't do all i'd done before but that's the adjustments i talked about.

i was on copaxone for 10 yrs and did very well.
i would encourage your dh not to project too far into the future. with 6 kids he may be fearing he's going to lose you.

would he consider any short term counseling?
please stick with us as i'm sure others with more insight will respond.
