its much more than a job isn't it. its about self worth, self esteem, pride, fun, a tinsy bit of power, leadership, a job well done, helpfulness, happyness, supporting other people, changing peoples lives - yes you are - giving other people self esteem, pride, fun, happyness.
its not about the money - its about your independance and damned good hard work.
i think that if your husband can be as reasonable as any person should be then if you explain this to him - he should be happy for you and willing to put up with the inconvenience twice a week.
as your partner in life he should try to accomodate your happyness and self growth - if he doesn't he is indeed a tw*t
