I was forced to end a potential relationship because of his drinking

hello, not sure where to start. I met someone about a month ago, and we started to get to know each other. He admitted during the first few days of us talking that he was in recovery. For the most part, we had gotten along just fine. He was really sweet, romantic, and he made me feel safe. He's been going to therapy and it did really seem like he was trying to make progress. But this past Saturday night, he got blackout drunk and exposed a side of him that I've never seen. he cursed at me, called me stupid, and even threatened me with physical violence. the next morning, he said he didn't remember anything that happened. I made efforts to try to communicate what he did and how it made me feel. But ultimately, I realized that I didn't want to go through that situation again. I messaged him stating I am ending things. We spoke for a bit and then I blocked him. I don't really know how to feel if I'm being truthful. I just wish him the best.
