I'm so very happy you and your children are safe, now. That is a horribly scary scene you all had to endure.
I'm also glad you are availing yourself of the available help out there.
I guess I wasn't around when you were here the first time. I've worked in the DV field for many years (retired prosecutor, now still working in DV), and if there's anything I can ever help you with, please feel free to PM me. I can't offer legal advice but I know quite a bit about the system and what's available in the way of resources to help you and your kids recover.
Many hugs, so glad you made it out alive.
