I am so sorry you have to deal with this. It must have been a nightmare being married to this loser.
I know this probably isn’t what you’re looking for, but if I were in your shoes I would move far away. Start by choosing a new city to live in, then start looking for a job. I would just pack up and move. ❤️
I hope you find the continued strength you need. Sounds like you are an amazing mama. You are doing so much for your kids. Hang in there!
