I've been there, it's not fun. It's hard to be supportive (even though that's what you need to do) when someone is in a situation which is frustrating and ultimately impacts your whole family negatively. My husband is an attorney and after living through 3 different jobs, small practice, large practice, government, he finally followed his heart and is working in politics. So we made a major move here. He's never been happier. Support your husband, encourage him to find what he loves and go for it. In the long run he'll be happier once he finds something he truly likes.
