Boyfriend was drunk and insulted my disabled child?

My boyfriend got drunk with his friends and one mentioned a school and he said that would be good for your kid, she speaks cursive right? She’s nonverbal and has some words. I was super hurt by this. He ended up going over to their place to sleep over (because they had more drinks, he’s an alcoholic) and he didn’t even want to try to make up for the bad night. Just before all this he yelled at me and when they went to the store he was in his room and didn’t want to help me make food. (I drove to his place and brought food). He came out when they came back. I was super close to leaving because he clearly loves drinking more than me. Before he left with them I told him that he hurt me and he said cursive means to swear, that he wasn’t talking about her disability. This should be the last straw right?
