I'm sorry and unfortunately, there are judges (for some reason often female) who look down on women who have chosen abusive partners and want them to "work it out for the sake of the children."
Let me tell you what my children's therapists say - every single one that they've seen: the only way children can recover from the abuse (and even if you were the one abused, that affects the children) is to know in their heart of hearts that they don't need to be with him.
I got a bad judgment against me and just kept gathering evidence. I would be willing to bet money that your ex won't keep up the documented AA meetings and you can drag him
Back into court.
Meanwhile, I wish the Ghost of Christmas Future would visit that judge and show her what her life may look like in ten years if her partner becomes addicted to alcohol.
