Bread winner🍞

Who is the bread winner in the relationship boyfriend/husband or you ? Also how do you and your spouse half the bills ? If your spouse pays majority of everything does he ever complain about everything I'm part time I make $10 a hour I get paid every 2 weeks I bring home about 400 if I'm lucky . While my BF brings home about 800-900 . He always throws it in my face how I don't help as much as him but I don't even make close to what he makes. 
EDIT: I've been trying to get more hours at work I'm  currently 32 weeks pregnant I feel like no matter how many hours I get it still isn't good enough. I also do everything around the house I cook I clean I take care of his son more then his ex wife does like I feel like do so much and it just goes unappreciated
