so tired of fighting..

I love my SO very much but we are only 19 and I am pregnant, we were planning it. But I just feel like he's not ready at all, I have to wake him up for work and he gets up 5 minutes before we have to leave, always works shorter shifts than he says he will. I'm just so tired of yelling and arguing about how he needs to get his priorities straight. I honestly don't know what to do I don't want to always be arguing but he's not even trying to get it together and I just feel like I work so much and even when I feel horrible I still work 11 hour shifts and I wake up and am ready and clean the house and pick up his trash. I have tried to sit down and have a conversation with him but it goes nowhere or we just end up arguing.😞
