There are a number of articles on the site that might help you from determining what your husband might be going through including suggestions what you might want to do.

Listening and learning as much as you can are the best things you can do, plus making sure to not forget to take care of yourself during this period--eating, sleeping, doing the best to manage the stress, having friends/family there for support, etc.

Keep us posted and if you don't find what you need, here or somewhere else, just leave another comment.

Good luck.
