I suggest that you talk again with your husband and explain why you want to earn your own money. Maybe it may help that you assure him that your relationship is strong and that you want to contribute for your future together.
If he has loads of ££££ (and the reason why he doesn't want you to work as there is no need for money) then you can tell him that you want to improve yourself. It is a self need which can only be satisfied by you working or going to college. It is also for your own mental health- For goodness sake, you are 23 yrs old you have your future ahead of you!
A valid reason is also that you want to help your family back in the Philippines and you do not want to rely to him for that money.
Talk to him heart to heart and I am positive he will understand
