Hi, Ovity.
Welcome.
Support is a good thing.
Nothing needs to happen this minute, so breathe, yeah?
Take the time, please, to educate yourself a bit about alcohol use disorder, which encompasses alcohol dependence and addiction.
It sounds like your SO is displaying pretty classic addict behavior: blaming you, claiming you are attacking him because you object to the drinking and smoking.
This not normal behavior. Most couples don’t act like this.
Keep telling yourself this.
It is easy for a partner to normalize dysfunctional behavior caused by overdrinking.
Al-anon, a group for people troubled by a loved one’s drinking, can be a great source of support, as well as your pastor.
Good luck. Keep coming back.
