I am so sorry that you are going through this. It sounds as if your husband not only has ADD but also has difficulty with impulse control. That can be a very dangerous combination when a person is angry. Its not hard to understand that you have been walking on eggshells and your son is not immune to the lack of problem-solving ability in your family.

Continue to seek support locally. You need a lawyer and both you and your son need counselling. Your son might also benefit from a child advocate to help him express his needs.

Your first responsibility is to provide what is best for your child. If your husband does not have you to abuse, he will, most likely, transfer it to your son. Call the police and seek protection for both you and your son.

Do it now.
