I'm sorry life is so rough right now and hope he manages to do better.
Now is a good time for you to find work that will help you and your children get by. No matter how he does, it is important that you are able to take care of yourself.
Meetings helped me regain my balance and you may want to try some as well. Live support is so important and will help you more than you know.
And we're here to walk with you. Hope your life takes a good turn soon.
Hugs
