How do I help my daughter - long story, sorry.?

[?LISA?]

I have 4 kids, 2 boys (22 and 17) and 2 girls (twins 20 yrs). All of the children still live at home. All but the youngest have jobs and one girl is in college and the other will start in the summer. I have always told my kids that when they graduate from high school, they must contribute to the household finances should they decide not to further their education. If they continue to college, they will not be expected to contribute because they would have to college expenses. My husband on the other hand still expects them to at least contribute to the utilities (about 50 dollars a month). This month my daughter gave him money at the beginning of the month. My husband is now telling her at the end of the month that she did not give him the money. They got into an argument and my husband called my daughter a horrible name. A name no father should call his daughter. This is not the first time he has done it. He also told my daughter (in anger) to leave the house. She left and went to stay with her boyfriend, which is not a good thing since he is 23, jobless, no money on probation and she pays for everything they do, his mother waits on him hand and foot and does nothing to encourage him to work and pay his own way. I don't know what to do. Even though my daughter is an adult, she is still my daughter and it aches that he is hurting because of her father. It also makes me angry that he could do that to his own child. I don't know how to explain what kind of man my husband is. As long as everything goes his way, it's a happy place, but once something does not go like he wants, all heck breaks loose. He calls people names, says he don't care about anybody and that he's going to leave and he don't care what we do. He's always yelling about something. You don't know what to say in front of him for fear he will fly off the handle for some reason. It's not like this all the time, but more times than not. I've asked him to leave because we can't continue to live like this and he just says he will leave when he is good and ready. I would leave myself, but I really have nowhere to go. Both my son's say that is just how their dad is and my daughters should just learn to ignore him, my other daughter just fights back. This daughter is the more sensitive one and is the one that gets most of his wrath. I told her she needs to sit down with her father and let him know how it makes her feel when he does this, but she says he just won't listen and I'm afraid she is right, when he knows he wrong he just continues to yell and talk over you and not let you get a word in and it doesn't solve anything. What should I do. I have suggested we all sit down as a family and let each other know how we feel and how other people make us feel so we can work on this issue, but I'm not sure it will do any good. Advise please.
