Dear 123sunnid,
It sounds as though you should explore your career issues with a disinterested third-party such as your mentor, therapist or pastor. I know next to nothing about floral design, but I do know that one should always pursue (within practical limits) any art that feels good. I began dabbling with music in my teens and if not for my singing in choirs and my instruments, I think that when my department director "retired" me from nursing would have been my last day on this planet.
You might feel out your employer and see if you can hold onto some kind of school nurse position, part-time if possible. In any event, do not let your nursing license expire. Without it, you close all doors in nursing after working so hard to get into the noble calling. There so many countless specialties that you can almost count on the
dream job coming along as soon as you let your license go.
Your husband should be happy that "his career is his hobby", but he should pray that it will continue as long as he needs it. I would ask him, "What would you do if you went to work tomorrow and your workplace no longer existed? What do you intend to do with your life after you retire?"
I loved my last nursing job so much that I told everyone that I intended to retire from there in another ten years. Big mistake! I always got the heaviest work-load and the worst EMTs or LPNs to work "with."
