2many,
I just have to add that your husband is not going to get better until he stops drinking and gets treatment for his bi-polar. This is also very abusive to your children to watch this kind of violence. If you are so scared just imagine how scared they must be. Something needs to change. I remember another post when your husband broke the table and pushed your child. This stress is so bad for you and so bad for your children. I hope you begin taking steps to make your life safer. Please go see a counselor.
Hugs,
MG
