Hate spending husbands money on me (even medical bills)

After the birth of our second child, a year ago, WE decided I would be a stay at home mom. Financial we couldn't/can't really afford it, but it makes the most sense due to other factors.

I love earning my own money and hate anyone spending money on me or asking for money from anyone, my spouse included. (Even married I have always had my own bank account). My husband has never said anything to make me feel like a burden but in the last few month I have been feeling like his money is his money. I'm very reluctant to ask even for things I really need. You would think it would help that in the past few month he has quit pulling his weight with housework and parenting. Also money is very tight, and he does a horrible job of managing a budget.

Any advice or can anyone relate? To feeling like a broke kid again? How to make husband stick to a written budget when it's 100% his money? How to not feel guilty (cause being a mom is a ft job)? (<<<equal hate this correlation, I'm not a nanny, I shouldn't be getting "paid")
