Can this relationship with my alcoholic, abusive boyfriend be saved without breaking up?

I’m 22 and my boyfriend is 22. We’ve been together for a year and living together for five months. The same day we moved in together, he got fired and was unemployed for three months, so I had to support both of us. He finally got a part-time job at McDonald’s a month ago, but during that whole time he was living off me and drinking heavily. He’s an alcoholic, and when he drinks he calls me names, insults me, yells at me, and stays in a bad mood all the time. We don’t sleep in the same room, there’s barely any affection, no cuddling, and no real intimacy, which really hurts me.

His car also got repossessed two months ago, so now he has to borrow my car. If I don’t let him use it, he gets angry and acts like I’m doing something wrong. When he gets drunk and loud at night, I ask him to be quiet because I don’t want us to get evicted, and he’ll yell that he doesn’t care if he gets us evicted. That makes no sense to me because he has nowhere else to go—he can’t stay with his mom, I don’t think his friends would take him in, and he also has a large aggressive dog. I do a lot for him and provide almost everything, so I don’t understand why he’s so unappreciative, mean, and careless toward me.

I care about him, but I feel hurt, drained, and stuck. Everyone keeps telling me to leave for my mental health, but I’m scared to break up because I don’t want to go back into the dating world. I just don’t know if this relationship can be fixed or if I’m holding onto something that’s already gone.
