"His" money

Tonight my husband said something really hurtful. We were talking about something I'm not even sure and my husband said I spend "his" money. I instantly got defensive. It was his decision for me to stay home. He even told me when I moved to the state he lives in he wanted me to take care of the kids and get them whatever they need. He works a full time job, volunteer job, then a contingency job and still doesn't make a whole lot of money. It's enough for us to get by and enjoy dinner out a couple nights a month. I was really hurt when he said I spend his money he makes at his job. I laid in bed crying over this I don't know if it's the pregnancy hormones (27 wks) or if he really is in fact in the wrong. How do I express my feelings without getting shut out? He has a habit of thinking he never says or does anything wrong but tomorrow through text he will apologize or justify it by saying "well you don't work so it is my money you spend, is it not?"
