I agree with giving your hubby your blessing to keep searching for something in his field. Don't ignore him because if he feels you do not support him then he feels worse. Just make sure he knows to leave your company on a good note - giving proper notice, keep working his best until the end, etc. I can't imagine the company not understanding that not everyone will be a perfect fit in their workplace. Your husband gave it an honest shot and it just isn't for him. He was brave to give it a try. He is seriously not happy and he needs your support and understanding. He does still have to be mature about it however, and not be a gloomy gus 24/7 as that is not fair to you and the kids. If you support him, he will feel better. If he looks for other work, that might help him too until he does find the right job. I'm sure he feels miserable that this did not work out, and feels very scared at the responsibility of keeping up the mortgage, etc. Hopefully he will turn his negative energy into a more positive and productive energy in finding a new job that is a better fit for him.
