That's what my alcoholic dad did when my mom finally got him to go to counseling. He blamed her and walked home. Trust me, this is affecting your kids a lot.
My dad said the same horrible nonsense to my mom, and I new what he was doing to her, before she knew it, and I was only like 12 years old. Save your kids....and yourself.
I understand it is hard to do the right thing, and it is way easier said then done.
