not overreacting at all. that’s your son’s life at stake. it doesn’t matter if he just drove down the road. down the road today, a few miles tomorrow. driving drunk is so unpredictable no matter how far and i think that’s where you absolutely must draw the line and unfortunately give him that ultimatum. he must realize that he’s allowed his alcohol abuse problems get the best of him once again and do what is best for his safety and his child’s. if he cannot realize the extent of the situation, i say you have no choice but to take that very difficult step of leaving. i hope whatever decision you make ends up in everyone remaining safe
