Boyfriend/Baby father issues

I’m the blue messages and the other messages are my “boyfriend”. We don’t live together until we save for our own place, so I stay with my parents. When we eat I try to bring him leftovers. Mind you we stay 15-20min away. I have to go visit him because money is tight and he has no transportation at the moment & sometimes he goes without eating if I don’t make him eat or if he doesn’t have enough money. When he say “us” he’s referring to his son(4yo) by another female. Mind you I’m pregnant and I haven’t ate all day or stirred around, just been in bed. I feel like he’s not worried about my well being by saying this. He gets mad just because I don’t skip, hop and jump when he tells me to. Since money is tight I like to eat before I go over there and get gas money from my parents if they offer instead using his money. We had an argument the other day because he notices EVERYTHING including how much gas I have in the car. When he got in he seen I didn’t have gas, but I hate asking for anything so I didn’t say anything. As we left the store he said why you didn’t tell me you needed gas? I said because you saw it and I didn’t feel mike I needed to ask. He said “closed mouths don’t get fed”. So today this is what happened. But he didn’t specify he didn’t eat all day, so I felt just like how he told me the other day closed mouths don’t get fed. But just because I don’t do what he says exactly when and how he wants me to it’s a problem. I feel like he’s being ungrateful and unsupportive/patient. He’s taking things out if proportion. What do you think of this though?
