Run away Owler. This man is not the one for you.
Words are meaningless. Only actions matter. And, for you, the only action that speaks is whether you stay or go. If you stay, your actions mean that you will accept a certain amount of abuse. That is the only message that you send to him. There is a very high likelihood that the abusive behavior will return.
Abuse and alcoholism are separate and different. The latter never, ever excuses the first.
Run away. Don't look back. Get this man out of your life.
