Thanks for reaching our for help. Firstly, does your husband realise that he has an anger management problem? Have your tried talking to him about it? It is him who needs counselling advise in this situation. There is only so much you can do unless he comes forward to accept and agree that this problem is big enough to warrant attention. Try talking him into taking psychological help to deal with his anger. You can also encourage him to take an appointment with a psychologist simply to clear his mind and get clarity because this anger might affect other areas of his life too.
Next Steps
Try to find the right time to talk to him about taking help for his anger issues.
Health Tips
Be cautious about how you tell him about how you feel. Most of the time, like you mentioned, anger shown towards the spouse can have deep rooted causes like being neglected as a child. So, his problem could very well be misplaced anger. Do not hold it against him. Give him the benefit of the doubt for now and try pushing him towards having a session with a psychologist or hypnotherapist. Every step you take will bear fruit.
