Alcohol boyfriend

My boyfriend is an alcoholic. Obviously he doesnt think he has a problem. We have been together 3 years. He is 31 and has a 6 year old son. We barely see his son because his ex likes to use the son to punish my boyfriend. Which makes him drink more. He drinks nearly everyday. And every weekend. One time he shoved me against the wall and another he twisted my wrist. He let a woman attack me twice while he was drinking and nearly allowed his brother to hit me. We recently got an apartment together and he is always on his phone texting and playing a pool game with his brother. Every weekend he leaves to drink with his brother and doesnt come back until the next day. The other night i was having contractions for 3hrs and he refused to take me to the hospital because he wanted to sleep. So i drove. I cant keep doing this. I ended an abusive marriage just to be in another abusive relationship it seems. Idk what to do. Im due to have this baby with the next few weeks and i feel more alone than ever! My family is a distance away and i feel trapped!! I love him but i cannot have him apart of my life the way he he is. He sees nothing wrong with his behavior, NOTHING! “Baby, you know i love you” is what i always get.
