Police wife

I know I've seen some police officers wives on here and I was just needing some advice I guess. How do you help with his stress from the job? What do you do when he's aggravated from all the calls he has had, and he takes it out on you? How do you handle being a police officers wife? I'm in no way saying I can't do it, I just need a little advice so I quit taking everything so literal. We have an 8 week old baby girl together and quitting is not an option. Times are just hard right now.. He agrees to work on things and so do I. We don't want to lose each other. We know we love each other. I just hate when we fight over stupid stuff cause he's aggravated.
