Well, after going through the entire thread, the answer to your question "husband or daughter (kids)?" is clearly: Husband. You are choosing the put your toxic, abusive husband over and above the welfare of your children. No matter how much advice you receive, it still always ends in the same thing - husband over children. Husband is #1. Saying things like "I can't leave him" etc, actually means: I don't want to leave him". End of.
We can only hope and pray you come to your senses and put your children first for once in your life. They don't deserve this. You are responsible for their welfare.
