Your fears are not unfounded. Crisis is always around the corner for any alcoholic and his family. And we should not try to prevent those crises. When an alcoholic is hit full force with the negative consequences of his drinking, again and again and again, he might realize that the problems in his life are directly the result of drinking and he might hit bottom and get some serious help.
If you are hoping crisis will not occur in your AH's life, then that means he would not be experiencing negative consequences again and again, which means he is manipulating his environment (including you) to support his drinking and succeeding in that. So he continues to get sicker and sicker. Addiction is a fatal disease.
Your choice is to decide if you are willing to live, with your child, at the mercy of someone's addiction. Your AH will not keep any promises he makes about drinking, and this includes whether or not he will drive drunk with your child in the car. This is the hard fact of addiction. He cannot control his drinking, anytime, anywhere, and to think he will be able to is to live in delusion and danger.
Your focus will be to decide what safety looks like for you and your child and to put a plan into place to achieve that. And sooner than later, because it is inevitable the next crisis is around the bend. This is the reality of addiction. It involves ongoing crisis.
Your fear is telling you your life is unstable and it is. We cannot predict what events will happen in the future. But with active alcoholism, we can always predict that until the alcoholic is solidly clean and sober, more sh** is about to rain down.
So rather than look at him and wonder how he is going to x, y, and z, look at you and your child and at this one goal: safety.
I'm glad you are in meetings and here. You'll need help to accept the reality of your situation and to make some very painful decisions based on the reality of alcoholism. Your fear is a good thing. If we see a tornado out ahead, we feel fear but we also get into action to take shelter to save ourselves and our children.
His alcoholism is a tornado. Your fear is telling you to get going with a plan to take shelter.
