I feel so depressed what should i do

I am12 weeks pregnant and I have an 11 month old daughter. My boyfriend got a new well paying job , we always been equals and struggled together to make ends meet. Well now he is making 3x more than me and is acting so greedy with his money , making me struggle and still wanting me to pay half for things. Obviously I'll pay the rent and bills I'm obligated to pay but our daughter needs clothes , Christmas is next week and her birthday less than a month . I financially can't do it alone and he is making me feel like I'm breaking a crime if I ask him to spend some of his money. He's like I Dont want to be broke again. I'm only spending $100 on Christmas , like really. Its stressing me out so bad . I can't even get him a gift and he is like why Dont you have money. Uhm because I paid all my bills sorry. My phone barely works and he is going out buying himself all new stuff , I understand its his money but we are a partnership , we live together , in pregnant and have a child with him. What would anyone else do , I feel like just quitting my job so he's obligated to spend his money cause how he's acting and say fuck all this stress
