Okay thanks for the additional information.
It seems that your husband's behavior isn't all that unreasonable. He doesn't act out over trivial things, and it's "normal" to worry about litigation, a home sale not going through, Chinese drywall, etc. Lots of people also get stressed when traveling abroad etc. That being said, what I would recommend is that you reassure him that if you do go back to work, that it's not letting you down and that you are fine with contributing financially (assuming that you are). Also, when he is stressed out, do allow him space to just worry and figure things out on his own. Asking him to talk about it, etc. may be counterproductive as men typically like to go in their "cave" when confronted with a problem and just sort things through in his own mind. If he can go into that place, undisturbed than he will come out sooner and be with you again, more like himself. What also can help someone who is prone to worry, is to tell him "okay, let's imagine the worst case scenario of what could happen, and then have a plan for that." This way, the worst fear already has a solution, if that should occur. Let him know that you two are a team and that together, you can come up with a solution and then execute it, if needed. Let him know that he is not letting you down, that you can work through whatever the problem is, and give him some time to just stress about it to himself.
