Hi, newmommy. Congratulations on your new baby! And thanks for stopping by.

It's important that you seek out support as soon as possible for a variety of reasons. For one thing, you need to document his behavior to see if there is a pattern to it. Second, it will be helpful for you to have an outside/third party to remind you of what is "acceptable" and what is not because as you continue to live with this situation, it can become all to easy to rationalize his behavior. Wives with abusive husbands slowly slip into acceptance mode. Third, a counselor can guide you through the next steps of either getting help for your husband or seeking safe refuge.
Your husband's anger problems (and we agree that an abusive childhood causes unresolved anger) are escalating to the point where he is causing undue stress. His demands are unreasonable. His reactions are way over-the-top, extreme, and unhealthy. Signs of something not right with his thinking or emotional state.
Yes, please seek counseling. A military counselor can insist that he comes for his own good, especially if a baby and a divorce are in the picture.
I always believe that people are worth fixing. You can take that thought into counseling with you. Just be aware that not all people believe they need fixing or want to be fixed. And some people will disagree with me here, but I believe that your baby is more important than your marriage. Protect your baby first.
I would think that with such a lovely wife and precious new baby, he has incentive to keep him family intact by getting some help. He needs someone else to show him that he is being harsh and unfair...and that he possibly has some type of disorder to manage. That you will leave if he doesn't do something about it.
A counselor can help you. Only you can determine when it is time to go but remember you have a vulnerable baby to protect. Will your husband repeat his abusive childhood?
