Didn't invite me

So my bf and me haven't seen each other in a few days bc he has a friend down visiting and I been talking to him all day and told him I didn't have anything planned tonight since it's just me and my 2 boys bc I didn't buy any fireworks bc I'm broke after paying rent and about 30 minutes ago I asked him if he was busy bc he hadn't responded back in an hour and he said he was doing fireworks. I was like damn didn't even think to invite us? He texts back that he asked me last week and he most definitely did not ask me last week bc I would have said sure bc I had no plans. Only thing he asked me last week was about going to monster trucks not anything about fireworks..
