Fighting with so..

I know it's probably hormones but me and my so have fought damn near every day for weeks! I honestly don't even understand what he be mad about. He just says "you don't listen to me, you don't give me sex, we spend too much money on food, stop telling me every 10 seconds that your pregnant don't you think I know?! I put him there". Dude. I'm 38 weeks pregnant I have 0 sex drive I'm fucking hungry and understand why I'm being a bitch if your tired of hearing it! He acts like be doesn't understand what pregnancy does to your mind and your body. Which I know he can't get the full picture but come on now. He's a battle rapper, if you don't know what that is he writes 3 3-4 minute rounds and he gets on a stage and goes against other rappers. I knew this when we got together but I didn't know the extent of the time it takes away. Just an example, I'm due April 28th he wants to take a battle on may 3rd. He doesn't understand why I feel this is inappropriate. It takes weeks of him staring at his phone writing these rounds and several hours a day on the phone talking to battle rapper friends. It drives me crazy I'm so tired of hearing it. And every time I try to explain to him that he shouldn't take this battle he says "I knew I was gonna have to quit battling for you I should have never started, I'll just give up my dream" that's not what I'm saying, what I'm trying to tell him is our son should be more important! Ugh. I love this man with everything in me our 2 year anniversary is 3 days before my due date I don't want to end up raising my child alone I don't want to lose my best friend. I don't know how to solve this situation. He never feels like he's wrong and I never feel like I'm wrong. It's so frustrating because we can never solve our problem. Idk what to do.
