Am I wrong for this?

So for the last 6 months I haven't been working cause that's what my boyfriends wanted. He owns his own business and thinks he makes a killing but doesn't really. Well today he went to work and made 40$ I usually don't complain but without a income we haven't had food in our fridge for weeks and been scraping change to feed my kids. He smokes pot and he decided to spend his $40 on pot well I scraped change to feed the kids. When I asked him he got mad and throw some things and said he is working for it he can spend it on whatever..am I wrong for being upset over this?
