Michele-
Your post says he's verbally abusive, especially when drinking too much. Is he that way sober or just when drinking? This situation is very close to me as my brother was a great guy sober, but terrible things came out of his mouth when he drank.
In any case, if it is more alcohol related, I'd definitely take him somewhere they don't have alcohol, like McDonald's and tell him the things he says while drinking. Record them if you can get your hands on a recorder. Sometimes they are seriously surprised at their actions. And he needs to be fully aware that you are considering taking the girls and living elsewhere, whatever it means. It helped with my brother, but his alcohol addiction was stronger than he was willing to let go, he lost his wife and two years later he died.
If your husband is, in general, verbally abusive even without drinking then the alcohol is an addiction that feeds his anger. You need to talk to him in a public place, tell him you need him to go to anger management, point out the things he does well as a husband and father, let him know he isn't 100% terrible, but ask why he is so angry that he would want to hurt you. Does he have a particularly stressful job? Ask how you can help him feel better about himself. Offer to go with him to meetings or find help, but he needs to know that without help, he cannot do it, and you cannot stay.
Another thing, this is hard, but evaluate yourself around him. Do you nag or complain to him a lot? How do you treat him, really, do you offer him love and respect? What do you say to other people or your daughters about him? Do you meet his needs? Do you dump on him at the end of the day saying how hard your life is? Or things around the house that he has not done? Or is your home the place he wants to come to, not dread? I DO NOT excuse his behavior, nor would I ever condone it, but sometimes we do need to take a step back and ask how we can improve ourselves in the situation, especially with children.
I pray you and he get the help you both need,
