Boyfriend don't want me to work ?

So I'm 3 weeks pp and honestly I'm ready to work again. So yesterday I started looking at jobs hiring and applied to one. My boyfriend told me he's not ready for me to work again and he doesn't want me to.. 
I mean I'd be fine being a stay at home mom, but I would also like some kind of income..I don't like when he spends money on me and I've told him that many times. I'm not the type of person to use someone else for their money, I want my own ! 
Is there something like an online job that can get me income ? I'm not sure what to do.
