Why not surprise your husband in preparing him his favorite meal and defuse some Essential Oils near him, while his eating the meal you prepared him.
I can tell you why not! Because he got stressed out sitting behind a desk all day while I was stressed out doing a heavy manual labor job all day!
Sure, I'm glad to spoil him a bit when I can, but I found your implication that the man's day is always harder (or he's the only one with a job) highly insulting. I work harder than he does. I often need a little relaxation and stress relief at the end of the day. I don't have the energy to take care of me, let alone him, too!
