How do I deal with an alcoholic boyfriend?

I’ve talked to my boyfriend about how it concerns me that he drinks bc he used to be an alcoholic. He made a lot of progress, cleaned himself up to be with me. but now it seems that he is drinking again. We went to one of his family parties and after we went back to his house, we were about to be intimate. I wasn’t comfortable bc of my past trauma and he was trying to convince me saying oh we are only this young once and pleading to do things to me. Him pleading was distasteful and making everything worse. I opened up to him about what had happened to me in that moment, to which he said yeah i’m not sure what to do, closed his eyes, and fell asleep. I was very upset and went home. He later told me he drank a lot at the party and that’s why he acted this way. He said he didn’t know how to act in the moment and he wasn’t sure what to say. Also, when we were in his room there were empty liquor bottles everywhere. Then the other night he called me and he was going through a family issue which angered him. He was threatening his family and repeating/slurring his words. He later told me he was drunk and it wouldn’t happen again. Then a few days ago when we were on the phone i noticed he was drinking. Making jokes about serious things, couldn’t remember anything we were talking about seconds later. He was picking fights with me and when i asked if he was drinking, he completely denied it. The next day, We had a long talk about it and he admitted to drinking and apologized. He was telling me that he’s going to stop and he doesn’t want to live his life like this, he doesn’t want me to have to deal with it because im the most important thing in his life. I also asked him if he thinks he needs to get a counselor and he said he is able to stop on his own. He says he will no longer drink heavily and only have one or two especially when he’s with me. it just is all so confusing and concerning. opinions pls
