I know what you mean! Fortunately, my husband has not yet lost his job, but I am constantly worried about what we should do if this happens, or if my husband gets sick. We have savings, but still I think that I should also earn money, although my husband does not force me to work.
In your situation, your husband needs to make an effort to find a new job. He does have some experience at his old job, though.
Unfortunately, I can't give you advice for you on how to earn more money.
