Please listen very carefully, with your heart, to the following...because it is one of the most true things I've ever learned:
YOU did not Cause HIS drinking.
YOU cannot Cure HIS drinking.
You cannot Control HIS drinking.
He's like you to believe you can do the three things above, because then he does not have to take responsibility for his life, his choices, his decisions, his drinking, his pain, his crappy treatment of you. It is all a BIG, FAT, GIANT LIE designed to keep you around so HE can CONTINUE DRINKING.
As for the single mom thing...you've got teenaged kids, not the easiest age bracket. But it'll be a piece of cake compared to caring for, cleaning up after and taking care of a man-sized infant.
Keep moving forward, you're doing great.
