Husbands help

Ni

FTM and my baby is two months old. Every since he has been born, my relationship with my husband has just gone to shit. I’m just overwhelmed and need help. I feel like I’m struggling bad just trying to balance everything. My husband works 16 hour days mostly, the day’s he’s off, I want him to help me as much as he can. Is this wrong of me? He says that he’s stress out taking care of everything else and I’m constantly nagging at him that he is not helping me enough. I know my husband has a lot on his plate but I still need help or at least a break here and there. We have been fighting so bad that he doesn’t know if he wants to stay in this relationship anymore...

Why are we struggling so bad? I’m just so overwhelmed and would like a break sometimes. :(
