When I was pregnant with #1, my AH got into a fistfight with a neighbor (both were drunk and got hauled away to sleep off the booze by the cops). My first reaction was that his behavior was unacceptable, that I didn't want to bring a child into that situation, and that I was going to move out the next day.
Almost 20 years later, I finally did. With wrecked credit, a wrecked career, and a horde of children with different mental health diagnoses all credited to "growing up with an addict parent."
I would not recommend to my worst enemy to have children with an addict. Ever. I would have been better off being a homeless singlem om than I was living with an alcoholic. And most of all, the children would have been healthier and happier.
