What is your advice on coping with their chosen career? Has the job directly affected your partners attitude or how they react to different situations?

Does your partner or you fear for their life? I've never been around anyone who has this as a career but my husband is currently in the academy to become one very soon. I'm so nervous and I've been having a hard time with him being gone all week while I'm home taking care of our kids (6 y.o, 3 y.o, & 4 weeks old). I'm also really scared about moving to a different city (2 1/2 hours away) where I don't know anyone ):
