Save my marriage and family

I don’t know what to do, I’m a new mom and I’m married but we’re struggling financially, bad. I just started back working and my husband lies about the money he makes. I don’t see the money since he’s been working and it’s been a month as well. He paid the rent last month but his mom helped him. He’s a good dad…very hands on! That’s what he’s supposed to do right? Unfortunately that’s not always the case…both of our biological dads weren’t around so I truly do appreciate him doing what he’s supposed to. He cooks and clean and gives me breaks/time to myself when needed. He’s good he just doesn’t have money n I’m sick of it. I work during the day so he’s home with our 4month old son….he’s works over night so I’m with him then…it helps us avoid daycare. I’m drained I told him if he doesn’t pay rent next month I’m leaving him n putting him out., am I wrong? We’ve had multiple conversations and I’m just sick of it. He didn’t do shit for my birthday because he didn’t have any money. Idk what to do??? Advice?? I’m too young for this! 25 I deserve better.
