Told boyfriend I don’t want another baby.

Boyfriend, and I have been together for three years, and have a two year old! He’s been drinking a lot lately, and every time he’s drunk, he likes to call me annoying, and try to tell me what to do! Telling me “lay down, shut up, and go to bed” rolling his eyes! Or is always saying degrading ass shit! He can never drink to just have a few drinks, he’s gotta drink to get tore up! I just told him today, that it would be seriously a mistake to have a baby with him right now when he can even respect me, or not degrade me! I’m sick of him drinking, or he needs to consume less! I’m not over reacting right?
