I don't know. But there is a saying, "nothing changes if nothing changes"
If you have left him "like the 100th time for his issues" than leaving and coming back is not working to bring sanity, serenity into your life or the life of your children.
A new plan is needed as you are see. You are powerless over him, just your decisions can only be based on what is best for the rest of the family.
Losing his family may or may not change his course but it can bring stability to yours.
If he is being verbally abusive maybe you can get a restraining order to keep him away from the house so you and the kids can live there.
