The SR members who gave you advice above me here are right.
I'll be less wordy.
There is no understanding it.
There is no getting through to your A.
Alcoholism is progressive and this will all get worse.
To be honest you are fighting a losing battle.
The BEST thing you can do is take care of you.
Get to Al-anon or Celebrate Recovery, or similar group for YOU.
Stop wasting your time and energy on trying to figure him and his alcoholism out, because the fact is, you won't.
Use your time and energy on yourself.
