Can't take any more

I really can't take this much more, but I have to for the kids. After 20 years with an alcoholic, I finally decided enough was enough. He was served divorce papers in May. I started dating prior to the divorce being final. Judge as many will, but I was miserable and had spent the past ten years of my marriage knowing that it was over but tried to keep it together for the kids.  When they grew old enough to start referring to their father as a drunk, and the 5th DWI came, I closed the door and started working towards a better future. We are now headed for trial to end this mess. (can't agree on a settlement as he hides income) As he now knows that I am dating, private investigators and videotapes=threats and blackmail for a settlement.  It is truly an UGLY divorce. Our house has become unbearable for everyone, especially our kids. He is angry and hurt and being vindictive at every corner, no matter how civil I try to be. I have already lost one of my jobs, my main income, because of his harassment. I just want OUT. Well, my emergency - tonight he has told my kids, ages 12, 14 and 17 that I was fired from my job for stealing (not true), that I am leaving him for another man (I left a drunk and met a nice guy), that I am a drug dealer (not true) and that I am trying to take every penny he has left from him.  THEN, he proceeds to offer to SHOW them the videotapes he has taken of me and my friend. From what he has told other people, videos were taken behind closed doors. Meanwhile, we all live under the same roof and I can't stop the vindictive behavior that is out of control and hurting the kids. Yes, I have a harassment order, but will use my actions to have him arrested against me with the kids. I can't leave with the kids until the judge orders a release on the agreed upon house items. We need out of here.
