How do you deal?

I love my husband dearly, but since we got married and joined accounts, I’ve noticed he thinks I’m his secretary/assistant. I He must think somehow that my job isn’t as demanding and asks me to take care of the stuff ‘he doesn’t have time for’. Recently he went on a business trip, had an issue with a toll and it was the first thing he said to me when he got home. “Can you take care of this toll issue?” When I told him no, he started sulking. #annoying
