Alcohol is my nightmare

I’ve been with my boyfriend for a year and a bit. I’m quite a bit younger than him. He has a drinking problem, and seems to get very emotionally, verbally abusive when he drinks whiskey. He is such a nice guy but once he drinks whiskey he HATES me. Absolutely hates me. I’m at a breaking point. Honestly, he works away for 2-4 weeks at a time and comes home and breaks my heart a little more everytime. He calls me down and my friends. And he just disappears. And leaves me at his house. Won’t invite me to come hangout with his friends (I’m not a drinker) but honestly I do love him. He used to apologize and try to make up to me. But now he just acts like nothing happened the next day. I’m not really sure what to do anymore.

Yes I’ve talked to him about it, but he just acts like I’m over reacting. I honestly think he convinces himself nothing happened, or I did something wrong.
