Jade, it seems to me that you do have a pretty full and interesting schedule.
I think some men do get stuck in a rut, he is perfectly content, as he has life served on a plate. He is the main breadwinner, he is the main earner, and frankly, if you get a job, he will either need to accommodate this, or not. I suspect he will be unwilling to do so, because he is used to the status quo and his job is "more important".
I think there are many unfulfilled wives out here!
The question is, how do you get him to realize that your happyness is important too? How do you get him to realize that it is because you have been running domestic life so smoothly and backing him in his working life, that he has been able to focus on his job and his career? How do you get him to realize it is your turn now, as you want to join the workforce.
He might be scared of this independence. Maybe you will even leave him? He should worry that you would, if he wont accommodate your hopes and aspirations too!
You need to have a long talk with him. Explain to him that you want to work too. You want to have a life beyond the domestic sphere. You matter. And for him to continue to have the back up of a good wife, he need to take on some parental responsibilities too. The alternative could be divorce with shared custody where he is full time dad one week, and "free" the next. Though, you rather he realized that he should make an effort so that you too could have a more interesting life.
