Seren was much more diplomatic than most of us.
When those of us who have lived with an active alcoholic see abuse (in any form) it is a MAJOR red flag that things are very wrong. This is not your doing, but his. He is unstable and unpredictable if he is using physical abuse as a tool. Abuse will get worse. You are the only one who can protect yourself, your kids and your dog. He will not because he is sick. That is how alcoholism and abuse work.
Al-anon will help you and so will therapy.
