Am I wrong for being upset?

We have no food at home, aside from bread, eggs, soup… (which the kids are tired of). Kids are home from school for a 4 day weekend. My bd gets paid today & we’re suppose to go get food after work. He now decides he’s going for a haircut after work & the food has to wait. Mind you he gets off late as it is, (7:30 & usually home by 830). We have a quince to attend tomorrow & I told him I’m not attending. It’s not a priority to me if putting food on the table for our kids isn’t one for him. I told him how hard is it to just get up at 9 tomorrow to get his hair cut & run whatever other errands we have tomorrow morning. & it’s just a huge deal for him. I’m also 8 weeks pregnant & just annoyed with anything & everything. Maybe I’m being dramatic… Ugh!
