On the verge of divorce

I despise and resent my husband. We have a 1 year old son and just found out I am pregnant again (unplanned). We have had a lot of bumps on our road. He has cheated, he is an alcoholic that would get completely out of hand, and our most pressing issue at the moment, his phone. I know it sounds dumb but he is so addicted to his phone, that he would rather sit there and scroll on Instagram then play with our son, or talk to me. Last night we had an argument because i asked if he would help put our son to bed, and he SCREAMED at me over it. He was just sitting there, on his phone. I get he works hard every day, but with another baby on the way, I’m going to need help! I tried talking to him about it this morning, but once again he yelled at me and told me to STFU and get out of his face. All I said was “my love language is quality time, do you know what yours is?” I may have my faults.. I may nag too much, get anxious easily, but I know I don’t deserve this. Would all of this be a deal breaker for you guys?
