Money madness overload!!!

My man and I worked on a car restoring it beauty. When it came time for the customer to pay he sent it to his phone. When I had asked him to send me some of the money he made excuses like we need food gas and whatever else. He does this every time but only when it comes to money. I’ve tried expressing myself to him multiple different times, trying to get him to understand how it makes me feel. I have been looking for a job but he comes across these extra jobs and asks if I’d like to help out. I’m 7 months pregnant so getting a job is not on the easy side of things for me. I guess my issue. is am I in the wrong for even requesting this money seems how we are in a relationship? I mean I just want to feel like I’m contributing but can’t shake the feeling like I’m useless. I feel like I have no control over any aspect of my financial future although I had also put in the hard labor to receive something that would make me feel as though I accomplished something for myself to. Am I right, Or am I just overreacting?
