Thanks for your question. My name is XXXXX XXXXX I'd like to help you out.
I'm sorry to hear about what you've been going through with your husband, and I would imagine this is very frustrating now that you are starting to feel better yourself. It sounds like you are correct that he needs anger management.
There may not be a perfect way to suggest this without him getting upset or defensive. However, it can help to have specific incidents in mind as examples of his anger getting out of control, as opposed to approaching him with more general comments that he needs help with his anger. He may attempt to blame you for causing him to get angry, but even if he has a right to be angry about certain things, he also has a responsibility to handle his anger more effectively. That is the main point of the conversation.
If you are at the point where it is causing you depression and there is this feeling of never knowing when an explosion may occur, then these are very concrete signs that his anger is affecting you, and that he needs help. In general, the more you can stick to the facts and point out the classic signs of anger management problems, the easier it will be to keep the conversation objective and less about how you feel. Sometimes people with anger issues are quick to get defensive and aren't always receptive at first. In general, the more you can keep your cool and stick to the facts, the more likely that he will start to give it some thought in his own time even if he has a hard time hearing this at first.
I know this is not an easy conversation to have and I definitely wish you the best with all of this. If there is anything else I can do to help please let me know.
