It sounds like your wife is in deep grief. MS is torment, and she might be processing that grief for the rest of her life. She may not have space for a romance at all. That may never change. Sometimes, MS doesn’t let you get “back to normal”.
It is deeply crucial that you get everyone to counseling now, and not just individually but in spouse and group sessions. As much as you can afford. You have already started a new dynamic and grieving your old one is natural. But you can still support each other and it’s important to do the work and figure out what that looks like.
Partnerships can be loving and supportive and caring and not romantic. Sometimes it’s a phase that comes back to romance, sometimes not. But you need to be ready to relearn a lot of things and that starts with counseling.
Edit: And oh my gosh, I should have led with this - I’m so sorry y’all are going through this. It’s incredibly hard and I hope you get the help you need.
I gotta tell ya, “is planning on increasing corporate taxes” seems like the right direction to me. So, yes.
