Oh my gosh WTBH! Your ex is the kind of person horror movies are made about, and the kind of person I have nightmares about. I realize that many here, including me, advocated for you to do the right things and have confidence that justice would prevail, but even I was beginning to wonder if it actually would. You've got to be one of the top five strongest and bravest people I know. I am so proud of how you are handling this, although nobody should ever have to "handle" anything like this.
You will be okay. Your children will be okay. His karma is finally catching up with him and it's not going to be pretty. Whatever you do, don't let your guard down. He's proven that he will not take his consequences well and it seems the consequences are only just beginning. Please do everything you can to keep yourself and your children safe!
All my most positive vibes are going out to you!
