"I cannot believe he would drive home with our ds in the car".
If I knew anyone that was drunk and drove a car, I would report them to the police.
If they were drunk and drove a car with my children in it, I would report them to the police.
And they would be looking for somewhere else to live.
And possibly looking to locate their teeth.
I couldn't continue a relationship with someone who has so little regard for the safety of my child.
