I sincerely hope that you know what you are doing. He has been physically violent with you in the past and you are now living with him again?
What are your bounderies? Is he aware of them?
Have you spoken to your attorney about taking the children with you?
I just have questions, no answers, again it is your children who must be the priorty, your daughter is already having issues as evidenced by her school drawings and now the drunken bully is back in the house with her 24/7. Not my business, but it concerns me.
I hope this all works out for you.
